The Ratt Fantomen Contest (which translates to The Right Phantom Contest) was held by Semic Press in Sweden in 1965. The contest required the reader to select the correct comic strip panel appearing in the comic book containing contest from an option of 5 images. The front cover of edition number 7 containing the contest can be seen below.

Found on page 36 of the comic book, we see a full page advertisement promoting the contest. The contest was held only in this edition, requiring the reader to select the correct comic strip panel as found in the comic strip story published within the comic book. A coupon was then required to be posted to the publisher with the correct answer written on the coupon, with the entrants address details.
