Vintage letterhead, SINCLAIR REFINING COMPANY T. J. Harvard Jr. Branch Manager San Antonio Texas, with a nice Sinclair Oils logo, in n-mint+ unused new old stock condition. Nice clean letterhead. Scans show the whole letterhead and a close up of the advertising. Size is 8 1/2" x 11". The black border is so all the edges can be seen and is not part of the letterhead itself. NOTE: The advertising letterheads I have listed are guaranteed to be 100% authentic originals. They are all clean, unused and new old stock unless otherwise noted. Thank you for your purchase I appreciate it.
