I didn't research the years and mainly noticed at least two spin racks with identical comics. That *never* happened around here unless some kid stuck it there without paying attention (and surprisingly that didn't happen that often - not like today). If there were too many copies of a particular title for a slot they just kept the extras behind the counter and refilled as necessary. There's also just one copy of each title in each slot. That rarely happened for that many books.The nitpicker in me has to ask... was that scene set in early 1960?
Because Brave and the Bold 28 (bottom left) was released right at the new year.
And after some research, that's Flash 111 on the right, also March 1960 coverdate released at the New Year, Adventure 273 with a June 1960 coverdate (so, a March-ish release), Detective 277 March 1960, Wonder Woman 117 from October 1960, and Superman 137 May 1960.
So they were all from the same year. Though a newsstand likely would've long since stripped or returned the March coverdate books for credit by the time the October books were out.
But there's probably only about a thousand people left who would care that much, so it is decently accurate.
