Two vintage U.S. Coast Guard pamphlets. "Oil Pollution Control for Tankermen" which was published in June 1975 has 44 pages and discusses water pollution and laws. The second is "United States Coast Guard" which has 15 pages and gives information about that branch of the military and discusses: establishment, duties, operations in peace and war. I think is from 1926. There is a logo on the back which shows a liberty bell with the dates 1776-1926.
Both are in fairly good condition the water pollution booklet has some stains on the covers.
