When I was a your teen I would read these types of magazines all the time. Keeping up on my favorite groups like the Monkees, Paul Revere and the Raiders and Buffalo Springfield. In this issue there is a Ad for Papermate Ops N Pops pens and on the back is a Ad for Lindy Pens. In 1967 Lindy Pens had twelve different colors.
If you go to YouTube and search Papermate Ops N Pops pens you will see some old ads plus a Ops N Pops dance contest.
I will post my collection again soon. Great pens that are no more.
