The listing, Vintage ESSO GAS Key Chain w Tiger EXXON / ENCO has ended.
Up for bid is a vintage (mid 60s I think) Esso key chain. It's bronze, and doesn't scan particularly well. I've shown it with the chain, and without in an enlarged size, so hopefully you can see most of the detail.
Front says: "Put a Tiger in Your Tank", and has a raised Esso mascot on the front. The Esso logo is just under the tiger head.
The back reads: "Drop It In Any Mailbox ~ Postage Guaranteed" around the outside of the circle, and "Happy Motoring Key Club (member number) G104727", Box 52008, Houston, Texas 77052".
The chain has "Ball Chain ~ Mt. Vernon, N.Y." on the closure.

Nice little collectible, and in pretty nice condition! Found at an estate sale, last month! Thought someone might like this for their collection. Check my auctions for another vintage advertising key fob in good condition!
