Shoes Required

My daughter, Amelia, and I joined a fellow stay-at-home dad and his two girls for a trip to the USS Constitution in Charlestown, Mass., recently. I brought along my camera, of course, but wasn't expecting this advertising nugget:

I searched online and found photos of this great sign before it was restored, but I don't know when that was done. Some folks indicate that the sign dates to around World War II, but I don't know.
