I recall reading somewhere that the size of original art changed during the sixties. Could anyone fill me in on the details of this? Did all publishers use the same size? If so, did they make the switch at the same time? What was the original size and has there only been one change? Did the publishers supply the drawing paper or board to the artists? If not, were the artists constrained to use the same size even if they were providing it themselves, because of the publisher's needs for uniform-size lettering and such? And why did the change occur at all?
I am particularly interested on when the art size at Marvel changed, though I am interested in the broader aspects of the subject as well. Recently I was rereading the Essential Capt. America Vol. 1 and I noticed that something was different about Kirby's art before the Gil Kane issues and afterwards. Although one of the first Kirby comics I ever read was a reprint of one of these immediate post-Kane issues and it has its appeal even now, it just seems to lack something that the earlier issues have, and I wondered if Kirby was initially having trouble adjusting to the change in art size.
