Ochs, Ernest - Aetna Brewery, New York. ... Not soda but "Beer" ... I include it here only because it's the oldestconfirmeddate I have found so far on a crown bottle cap ... circa 1902-06. The next closest date was from around 1910. Most seen on this thread are from the 1930s and 40s.
Polly Wolly ... Duluth, Minn. At first I wasn't going to post this one (I have about 200 caps on file) but I liked how the name rhymed so I decided to include it.
Popeye ... 1930s ... I think most of us have seen this one a time or two. But I didn't feel this thread would be complete without my ole sailor buddy. (Possibly one of the rarest of the rare). This is the only one known to exist and sold for $162.50
Re ~ O ... Oops! Out of order. Memphis, Tenn. Nothing super special here. But there was mention of the brand recently on another thread, so I thought I'd include it. Not sure of the date.
