For decades this clock, on the Kaufmann’s department store at the corner of Fifth Avenue and Smithfield Street, marked the busiest corner of Pittsburgh’s retail district. “Under the clock” was the designated meeting-place downtown, and Kaufmann’s premier restaurant was called the Tic-Toc in its honor.

The Kaufmann’s building (like everything else) is being redeveloped as condominium apartments, and the clock is featured prominently in the advertising art.
