Commercial cover from S.W. Coggeshall, a Newport, RI hardware dealer. What makes this cover so interesting to me is that Mr. Coggeshall lived in the house right behind ours when we lived in Newport from 1951 to 1956. Although long retired, he was still quite active and he had a big patch of Rhubarb in his backyard. When I was around 6 or 7 years old, myself and several other hooligans discovered the Rhubarb. We used to raid "Old Man Coggeshall's" Rhubarb Patch on a regular basis. Of course we frequently got caught and earned a good whipping  from our parents.
