Overview

Wisconsin Souvenir Milkcaps is a company based in Oconomowoc, Wisconsin, that produces collectible souvenir milkcaps and pull-tab promotions. The business grew out of an idea by founder Walter Bohrer, who studied Wisconsin state statutes and the history of milkcaps — the round paperboard bottle-tops once used by dairies to seal glass milk bottles. According to the company's website, Bohrer's concept began roughly nineteen years before the site text was written, drawing on the horse-and-buggy era when milk was delivered door to door and milkcaps sometimes carried prizes for customers. Collecting milkcaps had long been a hobby for Bohrer, and he turned that pastime into a promotion business known as Wisconsin Souvenir Milkcap Promotions. The company's history includes significant legal challenges. Its website states that the authenticity of the promotion was contested, leading to what it describes as enormous attorney fees and endless research time. The first legal decision was a victory against the City of Milwaukee and the Attorney General of Wisconsin. That winning judgment was then appealed by the Attorney General's office, and the Appellate Court ruled Wisconsin Souvenir Promotions legal. These battles are presented by the company as central to its identity and legitimacy. Wisconsin Souvenir Milkcaps operates in a niche that blends nostalgia, collectibles, and promotional gaming. Its products are milkcaps — round paperboard discs, historically made of two layers of stiff board with a flip-up pulltab secured by a staple, designed to fit snugly in a groove on the inside of a bottle neck. The company also produces pull-tabs, a form of charitable or promotional gaming common in Wisconsin. Its market is primarily Wisconsin, where such promotions are regulated under state law. The brand positions itself as both a keeper of dairy-era heritage and a legal, regulated promotion operator. Its website educates visitors on the history of milkcaps, their collectible value, and the game played with them. While the company does not disclose detailed financial or ownership information publicly, it remains active and sells through its website, wimilkcaps.com.

History

Wisconsin Souvenir Milkcaps traces its origins to founder Walter Bohrer's long-standing hobby of collecting milkcaps — the round paperboard closures used on glass milk bottles. According to the company's website, Bohrer studied the Wisconsin State Statutes and other promotions legal in Wisconsin before launching his idea. The concept reached back about a hundred years to the horse-and-buggy era, when milk was delivered door to door in glass bottles and milkcaps sometimes offered customers prizes. Bohrer's idea became known as Wisconsin Souvenir Milkcap Promotions. The company's early years were marked by legal conflict. Its website states that the authenticity of the promotion was challenged, resulting in enormous attorney fees and endless research time. The first legal decision was a victory against the City of Milwaukee and the Attorney General of Wisconsin. The Attorney General's office appealed that winning judgment, and the Appellate Court ruled Wisconsin Souvenir Promotions legal. These events are presented by the company as foundational to its legitimacy and its identity as a regulated promotion operator. Beyond the legal battles, the business is built on the history and collectibility of milkcaps. The company educates its audience on three main aspects: the history of the milkcap, its collectible value, and the game played using them. Historically, milkcaps were made of two layers of stiff board with a flip-up pulltab secured by a staple, fitting snugly into a groove on the inside of the bottle neck. Some classic dairies still use them. Today milkcaps are a collectible item, and Wisconsin Souvenir Milkcaps produces souvenir versions and pull-tab promotions, primarily serving the Wisconsin market where such promotions are regulated. The company remains active and sells through its website, wimilkcaps.com.
