My thanks to 'stevezodiac' for letting me post this image of his on my blog. It's an ad for Wham! No.1 which appeared on the back cover of Today magazine in June 1964. I'd never seen this ad before and thought it'd be a nice little item to show here.
It's interesting to see the Wham! logo in a simple red spot colour. If the comic had been published 10 or 20 years earlier that's possibly how it would have looked, instead of the full colour cover it had in 1964.
