I found this cool printing plate for a Bicycle 86 Rider Back tuck box. It's especially cool to me because I collect Bicycle cards and my wife is a printer. We both appreciate it from different perspectives.
There are a few questions that I'm hoping to get help with.
1) Dating it. It's a two color box, I'm guessing 70s but not sure. The boxes I've found that look like possibilities, also have a gold outline around the front of the box and I'm not sure if they would have used a three-color process which would have required two additional plates and not just one.
2) What are the notches at the top and bottom? I thought it may be intentional when they are taken out of service.
3) Once I figure out what boxes this printed, I'd like to find 2 example in excellent condition (one red, one blue) to include in the display when I get it matted and framed.
Any help is appreciated.
