Comes from a huge 1940’s group from Collect Auctions.  I’ve been through thousands from this collection, and they’ve all been great.
Very clean condition.
I do combine shipping, for all 3×5, shipping is $5, no extra for buying more.  Buy 1 or 100, shipping is still $5.  Just add items to your cart and request an invoice.
I guarantee authenticity on all my autos FOR LIFE.  Just save the ebay page as a receipt.  I am not a dealer, I just sell extras from large groups I buy to support my collection.
