In 1928, Timmins illustrated several automobile tire ads for Seiberling and B. F Goodrich. The versions I’ve encountered are all two-page ads. I find these ad illustrations interesting because they show a different aspect of Timmins’ talent. The Seiberling ads below contain rich figurative work and are delightfully colorful. The Goodrich ad below is a colorful landscape. For each ad, I’ve posted only the page containing the illustration.
