Vintage 1964 dial-a-"CHEVY"deal Adding Machine in Original Box

This item is a rare vintage promotional pocket adding machine titled 'dial-a-CHEVY deal,' specifically produced as a sales tool for Chevrolet dealerships in 1964. The object shown is the original cardboard storage box, featuring a mid-century graphic design with a bold red, white, and black color scheme. The text on the box reads: 'CHEVROLET GIVES MORE FOR '64! HELP YOUR CUSTOMERS SEE THE MONEY DIFFERENCE WITH YOUR dial-a-CHEVY deal ADDING MACHINE.' The box likely houses a stylus-operated slide or dial adder made of metal or plastic. Physically, the box shows minor edge wear, typical for a paper ephemera item of this age, but remains in good collectible condition with the printing still vibrant and legible. It serves as a significant piece of automotive advertising history, designed to facilitate price negotiations on the showroom floor during the 1964 model year. The typography and circular graphic element in the upper right suggest a mechanical theme consistent with the era's technical aesthetic. Notable features include the specific '64' date reference, providing an exact provenance for the item.
