The Fantomet Klubben Ring Advertisement appears in Fantomet comic book number 97, published by Interpresse in Denmark in 1978. The front and back cover of this edition can be seen below, with cover art completed by Rolf Gohs.

On the inside front cover, we see a black and white advertisement for a Phantom skull ring. The comic book reader was required to send payment with the provided coupon to an address in Bagsværd, Denmark. A discount was proved to Fantomet Klubben (Phantom Club) members, with the membership number required to be noted on the coupon.

The text translated from English to Danish reads:
