Though the Chudnow Museum of Yesteryear may seem new to me and you, much of the collection has actually been in situ for more than a decade at 839 N. 11th St., a big old house facing the freeway. The home was formerly the office of Avrum Chudnow, who was an avid collector of memorabilia and ephemera from Milwaukee's past, and Chudnow displayed many of the items there, beginning in 1991.
