4 vintage "Memo To File" notepads early 1960s

Description

This listing is for 4, unused "Memo To File" notepads from, I believe the early 1960s.  The pads measures about 8.5 by 11 inches and have about 50 sheets in each pad.
The pads are in good vintage condition though there is some discoloration on the top sheets of each pad.
