3 or 4?
Three-wheel carriage in Francr, 1828-1855.
Hardly anyone would think over how many wheels should be there on the cart:
3 or 4? Definitely 4! But the French preferred 3 wheels on a cart in 19th
century. Between 1828 and 1855 owners of three-wheeled carriages avoided
taxes which were applied to four-wheeled carriages only.
