The Rex bottles from Philly are really cool because they come in various colors, with different street addresses. I never saw this kelly green color until we dug a privy in August 2022 that had a couple. I kept one. My digging partner sold one on ebay for $675. And here is the third example. I very lightly polish cleaned it to help the color pop. It has an applied double taper top and a smooth-based bottom.
Embossed: W. M. REX / 211 GREEN STREET
Height: 7 1/2"
Color: apple-hued light kelly green
