Here is a card catalog that's been sitting in a folder in my desk since 1968. It is from Card Collector's Company in Franklin Square NY, dated Jan 15, 1968. It measures 6" x 9", and is 10 pages.
Complete sets of 1966 and 1967 for $13.95 each!
The left side of page 5, and the right side of page 4:
(These pages are stuck together in a few spots by the gum that oozed out from the order-form envelope between them. The left side of page 4 listed the Fleer baseball sets, while the right side of page 5 included the Philly Gum (1964-67) and Bowman football cards.)
Page 10: (I'd love to have that cabinet!)
I also have a 1967 catalog from another company, measuring 8 1/2" x 11", which I will post another time.
