Above are two Technicolor lithos of popular model Terry Higgins, who we also saw years ago in the Goodtime Weekly Calendar of 1963. You’ve noticed that these two shots are from the same session, but that the background color has miraculously changed. That was common with pin-up lithographs. We suspect they did it in pre-press, rather than in the photography studio with lighting, but either way it’s a neat trick. Higgins made appearances on the covers of men’s magazines such as Adam (U.S.A.), Candid, Tip Top, Folies de Paris et de Hollywood, and many others. She also starred in some nudie loops and had an uncredited appearance in 1963’s The Nutty Professor. The above shots are by famed lensman Ron Vogel, and date from around 1960.
It's a woman's prerogative to change her backdrop.
