eBay Saturday: Capt. Joe Keating's Showboat Inn Mug

Calling all Greenwich historians and restaurant buffs.

As you know, eBay Saturday features unusual items on the ubiquitous auction website of items related to Greenwich. This one caught our eye.

If you're looking to expand your collection of Greenwich-oriented ephemera, the seller of this milk glass coffee mug from the former Showboat Inn that was owned by Capt. Joe Keating, describes the mug to be in "excellent condition."

The Showboat—located on Greenwich Harbor, across from the town's ferry docks—closed years ago. Now it's the home of the posh Delamar hotel and l'escale restaurant.

The mug is up for bidding for 29 days, although the owner has a buy-it-now price of $15 plus $6.50 for shipping.
