Collection includes @ 350 magazines with CHECK THE OIL issues starting November 1994 until April 2019 and PETROLEUM COLLECTIBLES starting January 1997 to present. CHECK THE OIL was never a monthly magazine as PETROLEUM COLLECTIBLES was, so there are fewer issues. All dates should be complete from the earliest issues pictured until up to the present unless noted. Lots of interesting facts and histories of the gas/oil industry as well as collecting. Very interesting to see the prices of different items in the classified sections with comparison to today's prices. Must pick up in Clarksville, Tn. Container of mags is very heavy. Selling at <$1 each. $250.
