Before 1900, almost all bottled beer was sealed with a piece of cork just as wine bottles are today. The "bottle corkpull" was a miniature metal reproduction of a 12-ounce beer bottle containing a hidden corkscrew for removing the corks from bottles of Budweiser. On the front of the "bottle corkpull" was a small shield imprinted with the Anheuser-Busch "A & Eagle" logo. To use it, one would unscrew the top, raise the corkscrew up, turn it at a right angle, and screw the top back on, thus creating a "T" shaped corkpull. After opening the corked bottle of Budweiser, a gentleman could return the corkscrew into the metal bottle, screw it shut, and place it in his pocket without fear of being "stuck" by the corkscrew. Produced by the Williamson Co. of Newark, N.J., this utilitarian promotional piece proved a popular giveaway, particularly at the 1904 St. Louis World's Fair where tens of thousands were distributed. Because Anheuser-Busch continued to cork beer into the 1910s, even after the company began using metal beer caps in 1903, the "bottle corkpull" remained a popular item in the brewery's vast array of promotional pieces. -- taken from anheuser-bush.com. This corkscrew has some brassing around the top of the label (see pictures below) and some other wear from handling, but this is still one of the better ones that I have seen.
