MtheGM: I wonder if what you saw wasn't Arthur Treacher's Fish and Chips?

Arthur Treacher was an English actor who was famous in America for playing the butler in several Shirley Temple films, among others. I don't know if he ever used a bowler hat and umbrella in his films, but he certainly did in this album-cover photo.

It wouldn't surprise me if the restaurant chain used the bowler and brolly as symbols, since the whole point of its name and décor was to emphasize the Englishness of the recipe.

As I recall, the fish & chips were served in wax paper that was printed to look like an English newspaper, probably The Times.
