The above name, Thomas Peacock, taken from Spann's Guide To Gibson, was a Gibson salesman from 1930-1939. The above business card clearly states that he was a South-Eastern Representative. Although simple in design, this card would have helped promote Gibson instruments during the period.
Interestingly, you may note the name under Thomas Peacock is Ethel S. Peapples. Please click Gibson Prewar Letters to see her actual signature on a letter from 1926.
