A Ship-Shaped Rambler

A snapshot of a ship-shaped building that's designated as "Rambler I" on its bow. A silhouette of a flying horse similar to Mobil's Pegasus logo is painted on the side of the building. I didn't spot any structures like it on Debra Jane Seltzer's Ship Buildings pages, and I haven't been able to determine where it might have been located and whether it's still standing.
