On #PretendToBeATimeTravelerDay we're going all the way back to 1909 to the corner of 13th and Pennsylvania and the Sigma Nu fraternity house. ⁠ Throughout the decades, the building changed residents and layout, but the 2nd floor windows remained the same. ⁠ Today, we know and and love it as thesinkboulder!⁠ ⁠ If you could go to any year (past or future), where would you go and why?⁠ ⁠ 📸: 1909 photo courtesy of CU Heritage Center⁠ 📸: 1973 photo courtesy of CU Heritage Center⁠ 📸: 2021 photo courtesy of Mona Lambrecht ⁠
