As a handy missing link to fill in some of the blanks in connecting TV Westerns, Toobworld Central would like to claim that whenever a portrait is shown in an episode of a Western, Jeremiah Crowley should be given credit as the artist.
At present the only example I can think of is that of the portrait of Tom Barkley which hangs over the fireplace in the Barkley mansion outside of Stockton, California (as seen in 'The Big Valley'.)
