Original negative San Francisco Municipal Railway Trolley Bus No. 754 No. 12 Line on South Van Ness and 17th in 1969. The Mohawk gasoline station is selling regular for 36.9. The B&W negative measures 2 1/4 x 3 1/4 inches and has a slight amount of silver residue on the emulsion side. Otherwise the negative is in excellent condition. Good luck biding.
