Caption on back of photograph reads: 'As there is no county fair for merchants to display their merchandise, many find that the annual Poly Royal is an excellent opportunity to place their wares before the public. Tractors, graders, plows, hay bailers, seeders, harrows, discs and cultivators shown.' The text on the back of the photograph also indicates it was included in the 1939 edition of the El Rodeo yearbook.
