This was a pinup done for Superman and Batman Magazine. I can’t find any reference to the magazine on the ‘net–don’t know why as it was apparently one of DC’s best selling items. It was sold through bookclubs in the States, and I guess it was a popular item for parents to get for their kids. We had a couple issues, and our kids loved them (to literal and figurative death, actually).
Ty did a bunch of pinups for these (a Wonder Woman, and a Green Lantern…and I have memories of a four-page pull out poster) and a mini-comic (can’t remember how many pages) based on Batman Adventures itself, or the style, written by Roger Stern.
Here’s the Hawkman…
