Leipp's Extra Pale Beer- "Uncle Sam" below: I couldn't believe how well preserved this ad was for as ancient as it must be. I haven't found a lot of information out about this company - apparently they were about the biggest brewery in all of Chicagoland at one time. They closed for good in 1933, but I think this one is from around the time of the Great War, if not earlier. The Pure Food Law went into effect in 1906. The building was a tavern/saloon as far back as 1907. -SH
