If your appetite for turn-of-the-century cobblestone roads and vaguely creepy, not-quite-life-sized storefronts has gone curiously unfilled this summer, there’s a reason for that. Milwaukee Public Museum’s iconic Streets of Old Milwaukee exhibit has been closed since August 3. The 50-year-old exhibit is currently undergoing a “reimagining,” and will open again in December 2015 with an enhanced “wow factor” and a “heightened sensory experience.” Move over, Bud Selig hologram!

Thankfully, MPM promises to keep much of Streets’ beloved character, though it apparently needs a little help to do so. Beginning today, a “Complete the Streets” campaign gives Milwaukeeans a chance to kick in a few bucks to put the finishing touches on the revamped exhibit. Want to see an old-school photography studio added to the Streets? MPM needs $500 to make it happen. How about an authentic Schloemer Motor Wagon? $6,000. Have you always wished there were smells that went along with the Streets’ darkened roads and unsettling mini-houses? Of course you have. MPM is looking for $1,000 to add some fresh bakery scents and make your retro olfactory dreams come true.
