I don't know anything about petroliana. My daughter found this sign buried on a beach of the Mississippi River.
Google showed me a kind of gas jar holder/ carrier with this same company on it, and an article that mentions the Campeco Oil company in a small town in Michigan. She is looking for any information about the history of the company, the age of the sign, the value of the sign.
Thank you in advance for any help you can give ☺️
Sorry, this is on a kitchen towel not a bath towel. Dimensions are approximately 9"x12" (eyeballing it)
