Vintage receipt, SINCLAIR MOTOR OIL and OPALINE LUBRICANTS, "Put "Spring Zing" in Your Car With This Sinclair-ize Special", in n-mint+ unused new old stock condition. Nice clean receipt. Size is 5 1/4" x 10 1/2". Scans show the front, back is blank. The black border is so all the edges can be seen and is not part of the receipt itself. NOTE: All of the receipts 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.
