Vintage magazine ad, MOBILGAS MOBIL Socony-Vacuum gas oil from 1947, picturing Pegasus Miles Ahead For Mileage. Ad may show minor imperfections consistent with age. Size is 10 1/4" x 13 7/8". Scans show the whole ad and a close up. The black border is so all the edges can be seen and is not part of the ad itself. NOTE: All of the magazine ads I have listed are guaranteed to be 100% authentic originals and come from my personal collection. They have been carefully removed from the magazine and kept in archival storage. Some are rare or very hard to find. Thank you for your purchase, I appreciate it.
