I have a set of porcelain cobalt 10" Esso Servicenter letters. I am looking for the larger rounded E and S for them. If anyone has extras or can point me toward these it would be greatly appreciated. These were all 10" on the station they came from and the owner had photos of them still up. Did Esso use various sizes and styles through the years? Had I not been shown the photos I would think they were just randomly put together. Thanks for any help.
