I have a bottle, I think it's tequila, that was in my grandparents' house for years. It's stamped on the bottom with "Federal Law Forbids Sale...", so I'm pretty sure it's liquor. It has what I take to be agave leaf molded into the glass. It's recessed, not raised, and the same leaf is also on either side of a gold band on the neck. The stopper is a "T" style, but trimmed off on one top side by design. Plastic stopper with cork plug to seal. Aside from the "Federal Law..." on the bottom, it has D-334, a 3 by itself, and 40-59 which I'm guessing is the 40th week of 1959. The bottle with stopper is 11" tall, 6" wide. Here's some pics, hope it helps. Even if we can't identify it, at least you folks can have a look. I always kiddingly called it their marijuana bottle, due to the shape of the leaf. Thanks!
