(3 1/2 x 5 1/2 In) This is an original vintage R. R. Donnelley & Sons Co., Deeptone postcard from the 1930s. It shows a view of a worker "Removing Firestone Gum-dipped Tire from Automatic Curing Mold in the Firestone Factory and Exhibition Building at the 1933 Century of Progress World's Fair in Chicago.

"FIRESTONE AUTOMATIC CURING MOLDS - After all the component parts of the tire have been assembled-- high-stretch Gum-Dipped cords--plies--beads-- two Extra Gum-Dipped Cord Plies under the Tread-- and the Tread Rubber itself-- the tire is placed in a gigantic curing mold. In this final important operation, the tire is forced by 43 tons pressure into the Firestone non-skid tread pattern engraved in steel mold and vulcanized by steam at 270 degrees F.", reads the description printed on the back.
