1930-1939 General Motors GM Good Housekeeping in Your Car How to Clean and Take Care of Upholstery Fabrics Booklet. Original.

This booklet discusses the care and cleaning of automobile upholstery. It presents specific methods for the removal of the more common types of spots and stains, such as candy, chewing gum, grease and oil, ink rust, etc. All these remedies have been tried and tested, and can be used with complete assurance of safety, if instructions are carefully followed (not so sure they would all be considered safe today - such as carbon tetrachloride).
