I picked up an ink etching at an antique store locally. The title is "An Englishman and a gentleman" by Dennis Morgan. It's a drawing in ink of an English bulldog. It is dated 1927 and hand signed and titled in pencil. Also the name of the dog(forget it at the moment) and "National champ" in ink.
I found a few in etchings online for sale by the same artist. How can I authenticate this is real? I don't know art I just like bulldogs....
