On June 17, Юрий Черданцев‎ (Iurii Cherdantsev), a former professor at Tomsk Polytechnic University, posted two photos to the public Facebook group, СТАРЫЙ ТОМСК: улочки, дома, судьбы томичей (OLD TOMSK: streets, buildings, lives of Tomsk residents). One was a photo from 17 June 1917, 100 years ago. It depicts a demonstration (one of many during that tumultuous year), organized by the Provisional Government. Our building (on what was then Post Office Street) is visible on the right-hand side of the photograph. The second photo shows roughly the same view in June 2017. I’ve copied and included them, here:
