A few items for me:
1950s Tydol Ethyl Gasoline Paper Kite:
1920s: 1 gallon Emergency Gas Can from Aetna Oil:
1926 Associated Oil Sales booklet for Attendants to help sell the new Ethyl Gasoline, 1956 Sunset Golden Eagle Ethyl Gasoline booklet and 1952 Atlantic Ethyl Gasoline booklet:
And lastly from Don Sherwood (email@example.com) from 1966:
I wonder if they will grow?
