Hi Pam, not sure about 209 East Second Street but my two examples from 224 E 4th show the phone #'s from that '46-'51 era and also info about the proprietors. Here's an obit for George Mross Jr. mentions "where his parents owned and operated Beckers Bar on Commercial Row and The Reno Bar on E. 4th Street" https://www.rgj.com/obituaries/rgj048238
