Hello!! Thanks so much for your interest! This is a large collection of 550+ vintage postcards. Estimate is conservative as the weight is over 6lb per box. I bought these cards as part of a massive buy-out from a local postcard show dealer that was retiring from the business. This is a mixture of $0.25 boxes, $0.50 boxes, $1 boxes, and special price boxes that may have been on display. Posted and unposted postcards. I tried to pull cards at random from different boxes but can not make any gauretees or take special requests. Photos only show a small bit of what we have. BUY 2 BOXES GET 15% OFF BUY 3 BOXES GET 20% OFF BUY 4+ BOXES GET 25% OFF Note: Boxes will be 99% USA Location. All are 4x6 contenental sized. Shipped securly within 48 hours via USPS.
