Photo of Uncle Ezra (announcer Pat Barnett who also performed the character on a separate radio show){left} and the Hoosier Hot Shots in a publicity photo for the National Barn Dance when it was carried by NBC Radio.

• Because the back appears to have been cut off in the original scan, a copyright search was done in artwork for the year 1935. NBC registered an audience analysis of typical evening broadcast programs, but not this photo. Kaufman-Fabry registered some photos in 1936 (the volumes are combined), but not in 1935. There's no evidence of original copyright for the photo.
