A few years ago I attended the art and antiques festival in Superior, AZ. One of the booths featured thousands of vintage postcards.
Liz and I spent well over an hour scouring the collection, and pulled out every postcard of the Superstition Mountains and wilderness. We donated the postcards to the Superstition Mountain Museum, but not before I made high resolution scans.
I have reproduced these postcards and they are available for purchase. The postcards are 5″x7″, on heavy card stock, and have a UV gloss coating on the front.
The images displayed are 13 of the 17 cards total. The complete package of 17 cards sells for $20. The postcards date from the 1940’s through the 1950’s.
