Description:Exhibit postcard vending machine c.1920-30s. Metal counter top vending machine has "Exhibit Supply Co's Cards" impressed in the lower front along with a 1925 patent date. For one penny the machine would dispense a single card to the user (unknown if in full working order but it accepts the coin and the slider goes in and comes fully out). Mild general wear consistent with use as intended and storage and the glass front is missing (could likely be replaced). Key not included: EX
