1906 V.O. Hammon Publications, Chicago #320 Postcard
I was born in Aurora IL, so this postcard has special meaning to me. It depicts a "Bunch of Baseball Fans" standing outside the Beacon-News Building (the town's newspaper published continuously since 1846) getting updates on the 1906 World Series between the Cubs and White Sox. There was probably a chalkboard in the window where ticker-tape updates were relayed and posted for all to see.
