"Journal-Guide to Oil Basins of the United States",

This detailed, linen-backed map was issued as a supplement to the Oil and Gas Journal (Volume 50, No. 46) by the Petroleum Publishing Company in Tulsa. The top left quadrant contains a map of the United States detailing the major oil basins in the lower 48 states. Below the map is a "formation correlator" which details geologic types by various geographic regions. The right half of the sheet consists of 23 geological cross-sections of the major oil basins with corresponding A-B red lines drawn on the map to show their respective paths.
