Defenders of the Earth Birthday Cards

The Defenders of the Earth Birthday Card series was produced by Gemma Designs Ltd in Andover, Hampshire, UK in 1989. The series contains a total of seven unique Birthday Cards, designed to be given to a child to celebrate their Birthday.

Established in the 1980s by founders Lindesay and Margaret Rudd-Clarke, Gemma International (frequently referred to as Gemma or Gemma Designs) was a prominent, family-run greeting card publisher based in Andover, Hampshire. The business initially sparked to life when the founders, who were independent toy retailers at the time, recognized a significant gap in the market for children’s greeting cards. They realized that the popular, trending characters dominating toy store shelves were noticeably missing from the greeting card aisles, and they set out to bridge that gap.

Over more than three decades in business, Gemma grew into a major player in the UK publishing industry by securing the licensing rights to some of the world’s biggest children’s entertainment brands. They designed, produced, and distributed millions of vibrant birthday cards, gift wraps, and partyware ranges featuring household names like Peppa Pig, Angry Birds, Ben 10, and PJ Masks. Their reach was vast, supplying everyone from large supermarket chains to independent boutiques, and they even operated a unique brokerage model to manage greeting card stock for major toy retailers like The Entertainer.

Despite their long-standing success and the launch of a boutique-focused sibling brand called Studio by Gemma, the company faced severe headwinds in an increasingly competitive retail landscape. In mid-2019, after 34 years of operation, managing director Amanda Parkin announced that despite drastic cost-cutting measures and attempts to find a buyer, the business would officially cease trading and enter voluntary liquidation. Though it is no longer operating, Gemma Designs is remembered warmly within the British stationery industry as a true pioneer of character-licensed children’s greeting cards.

The Defenders of the Earth Birthday Card are printed on heavy-stock paper in full gloss finish color, sequentially themed for ages 4 through 10 and includes a matching collectible badge/pin. Also included in the clear see-through plastic sleeve enclosing the card is a yellow paper envelope. All seven Birthday Cards can be viewed below.

Here is what is featured on each specific card:

  • Age 4 Card: Features the orphaned boy adopted by Mandrake the Magician, Kshin, dressed in his signature red jacket and yellow shirt, accompanied by the fuzzy, purple alien sidekick Zuffy. The pink badge also highlights Zuffy alongside a large number 4.
  • Age 5 Card: Features Flash Gordon’s son, Rick Gordon, dressed in his signature blue jacket against an icy background. The purple badge features Flash Gordon next to the number 5.
  • Age 6 Card: Displays Flash Gordon and his son, Rick Gordon, standing on a rocky ledge with a futuristic starfighter jet flying overhead. The red badge showcases the faces of Flash Gordon, The Phantom, and Mandrake the Magician around the number 6.
  • Age 7 Card: Showcases a dynamic pose of Flash Gordon wielding dual laser pistols with his starfighter in the background. The badge features a close-up profile of Flash Gordon with the number 7.
  • Age 8 Card: Highlights Mandrake the Magician in his iconic top hat and tuxedo cape, gesturing over a misty crystal ball or planet surface that reveals the villainous Ming the Merciless at the bottom. The badge features Mandrake’s portrait and the number 8.
  • Age 9 Card: Focuses on The Phantom in his signature purple costume and skull-emblem belt, standing in front of an Ice Robot. The matching orange-to-yellow gradient badge shows a close-up of The Phantom alongside the number 9.
  • Age 10 Card: Features the main antagonist, Ming the Merciless, riding his giant, ferocious python Mongor against a fiery sky. The blue badge mirrors this with a close-up portrait of Ming next to the number 10.

The interior and back exterior of all seven card contain the same print. When opening the Birthday Card, we find a plain white right-hand page printed with the franchise logo showing the text “DEFENDERS OF THE EARTH” over a line-art globe, positioned above a simple, lowercase “happy birthday” greeting, while a solid yellow envelope rests inside the left cover. The rear of the card showcases a full-color illustration enclosed in a blue and black diamond frame, depicting the four main heroes, Lothar, Mandrake the Magician, Flash Gordon, and The Phantom, beneath a yellow comic-style banner that reads, “EARTH IS IN PERIL!! WHO CAN SAVE US?”. Below this central image, the show’s stylized, colorful logo sits above a standard barcode, followed by production text confirming it was “Printed in England” by “Gemma Designs Ltd Andover SP10 3BB” with copyright marks dated 1989 for King Features Entertainment Inc and King Features Syndicate Inc.

Each of the Birthday cards is accompanied by a badge produced by Gemma Designs Ltd. They feature vibrant full color backgrounds dominated by a large, bold white numbers on the right side. To the left of the number, the badges showcases the illustrated heads of characters seen in the Defenders of the Earth cartoon series.
