This set was issued to mark the 50th Anniversary since the publication. Our sticker shows Desperate Dan, a cowboy character from the Dandy magazine, who turned into its figurehead.
He was there right from the start - the 4th of December 1937 - and you can see the cover at BritishComics.com/dandy
Sadly the Dandy is no more, poignantly the last edition was also the 4th of December, in 2012. The main reason for its failure was almost certainly the fact that it started out with many different genres of stories but slowly phased them out until only the funnies were left. Its move to a digital version in 2012 was also unsuccessful and lasted less than a year.
By the way, you can see the entire album for this set, and its contents, at : RetroFootballStickers/Beano - just click on a framed square to enlarge that page.
