From the November, 1974 cover-dated Marvels -- or at least one of them -- is this house ad that was stuck at the bottom of a letter column page. It's possible that there may have been a few different ones done, and they were put on different letter columns!
I do like this one, as minimal a size as it is (considering it's promoting Giant-Size books), because it not only tells you which books they're promoting, but give you a single line for each one to get you interested in them... plus there's an image clipped from the cover to whet your appetite!
I don't think I bought more than two Giant-Size Marvel titles off the racks... I know I did have Giant-Size Creatures (or whatever it was that introduced Greer Nelson's new persona of Tigra the Were-Woman) as well as Giant-Size Superstars (I think that was it... basically it was a Giant-Size FF book, featuring the Hulk Vs. the Thing with Rich Buckler imitating Kirby). Naturally, I probably don't have any Giant-Size books in my current meagre collection... but I do have the Giant-Size Marvel trade paperback (which, itself, is paradoxically one of the thinnest TPBs in my collection).
I am a former graphic designer turned medical assistant turned truck driver who's into comics, sf, tv, cartoons, monsters, oldies rock, and lots of other stuff.
