United States Crown Corporation stock certificate 1971 (bottle caps)
Great bottling collectible. Amazing vignette of the company's product - a flip top bottle cap. Issued and cancelled. Dated 1971 in the last year of operation.
Incorporated 1960, the company produced and marketed a flip top bottle cap that could be removed without the aid of a bottle opener. The manufacturing was complex and the application was never really picked up by bottling companies. The company was dissolved in 1971.
