The front of the building is a sports-apparel store, with the museum consisting of a large room in back. The museum was founded in 1986 by Ray Crump, originally a batboy for the Washington Senators who then moved with the team to Minnesota in 1961, becoming the first equipment manager for the Minnesota Twins.
Crump’s display includes artifacts he collected over the years with the Twins, including World Series bats, jerseys, autographed baseballs and photos, clubhouse books and displays on how to make baseball bats and gloves. There are also collectibles and memorabilia from the Beatles’ trip to Minnesota in 1965. The museum's glory is the colossal collection of vintage 1970s photos of Crump with a mélange of celebrity friends and acquaintances, including Conway Twitty, Loretta Lynn, Liberace, George Burns, Muhammad Ali and Tony Randall to name a few. Most of the snapshots are autographed with scrolling sentimental inscriptions. The museum's centerpiece is Crump's shrine to Elvis Presley, a mountain of memorabilia and autographed items. The highlight is a Minneapolis Star story about Presley's concert at the Carlton in 1977, which was dedicated to Crump and then-Twins owner Calvin Griffith.
The Washington County Historical Society is the proud parent organization of the St. Croix Vintage Base ball Club. The vintage base ball matches played in Minnesota emulate the game the way it was played between 1857 and 1865, after the nine-inning rule took effect but prior to the changing of the one-bound out rule. The minor rule variations that took place between these years are sometimes open for debate. A stealing rule, and occasionally other rules and conventions are agreed upon prior to the match. The clothing, setting, language and accoutrements can vary greatly from game to game and group to group. Many groups wear old uniforms, swing old-style bats and shout words not heard since the nineteenth century.
Three baseball eras are commonly enacted by museums, Civil War re-enactors and vintage base ball clubs today: the gentlemen’s period of 1857-1860 when the nine-inning game was new and the game was dubbed the “National Pastime,” the period during and just after the Civil War when the game became more skilled and its popularity spread throughout the growing nation, and the early professional years of the mid-1880s when blacks played alongside their white teammates and overhand pitching necessitated the first gloves for catchers.
