I don't have a full run of issues but I did note that sometime between issue 11 (5/15/61) and 16 (12/30/61) Woody Gelman turned over the editorship to Jim Zak of Cicero, Illinois, although it remained essentially a house organ for Gelman's Card Collectors Company, which still published the little 'zine.
First up, from number 19 (3/30/62) we get an issue date for the Bazooka Presidents set, namely 1962.
(UPDATE 6/23/20: It turns out it's from 1960 after all):
Later in the same issue we see that the 1962 Topps Baseball Stamps were being issued 40 at a time, at least in the beginning.
Anyhoo......Fleer's FTC complaint against Topps makes news. Fleer would win one of their arguments in 1965 before the decision was overturned and they sold all their player contracts to Topps in '66. Topps had 414 of 421 major leaguers locked up and Fleer took exception.
In issue 22 (6/20/62) we get one of the first inklings of the 1962 Baseball green tints:
Meanwhile issue #24 (8/20/.62) brings 1949 Bowman misprint sheets and 1952 Topps highs. Woody was really turning up some goodies!
