Unfortunately I have over 100,000 duplicates in about 130 automotive topics and no list. Mine are in boxes mostly sorted. What are your favorite topics? I used to set up at Hershey and Carlisle every year until gas got so expensive it was costing me $1,000 in gas just to get to Hershey one way in my 5 MPG motor home. I have sold all of my non automotive cards, over a million of them and just kept the automotive. If you are looking for a postcard on any specific car I can probably tell you what cards were made for that car and make copies if I do not have duplicates. I have a couple of hundred Kaiser-Frazer-Willys postcards in the 1946-1955 era and some duplicates. Many like dealership postcards are hard to find.
