Readers, we need your help to solve a mystery. In the 1950s, a map of the late Pan American World Airways System was on the south wall of the foyer of the future Auditorium in the HUB. Students signed the map—and we’d like to know if you recall seeing it or remember signing it. If so, we invite you to contact Paul Zuchowski, the HUB’s associate director and resident HUB historian, at badgers@uw.edu. (Yes, he went to that other UW.)—Jon Marmor
