Lovely black and white photo postcard showing A Welsh Corgi profile, titled "Welsh Corgi". "A Guy Withers Study 13." Made by Photo-Precision Ltd., St. Albans. English Series Post Card. Based on what I can find about this, it was probably printed in the 1950s.
It does not specify, but it does appear to me to be a Pembroke Welsh Corgi from that time period. I don't recall having seen any Cardigans from this time period.
Card is in condition as pictured. Unused, clean. Small penciling on back.
