Vintage general motor oil filter

vintage advertisement/ info from General Motor on the importance of changing the ac oil filter. All of the ads are from 1950s to 1960s LIFE and the Saturday Evening Post. Some have ands on both sides. Due to their age, some of the pages have discoloration around the edges. I tried to remove the ads as clean as possible but some need the edges trimmed with a paper cutter. Additional ads ship for free. #car #retro #vintage #automobile #oil
