With over a hundred walls of death traveling the US by the 1930s, perhaps the coolest version was the ‘Liondrome’ in which a rider is accompanied by a tamed lion. With stage names like “Lolita” and “Ethel Purtle” these fearless women [and that one man in the first photo] actually kept these lions for pets… driving them on vertical walls for fun and profit. To have a lion right behind you on your passenger seat would be quite risky (it might get a bit too stressed and bite your head off, you know), so the drivers placed them in side-cars, and were careful not to smell of alcohol while driving - lions absolutely hated it!
