Solomon Grundy's logo on the back was blacked out when mug was purchaed. Nail polish remover lightened the black square to show the restaurant name. Solomon Grundy's opened in 1968 and changed hands & was renamed in the early 1970's, so I assume the name was blacked out at the time ownership changed.
