They say America is the land of the free.
But it could also be described as the land of the outlandish, given the focus of some of its quirkier museums.
Here we present eight of the most unusual, attractions that are thriving despite their collections showcasing items that range from the peculiar to the peculiarly mundane.
There's the museum passionately devoted to a type of condiment, one that celebrates a popular variety of vegetable, a museum containing parts of Einstein's brain and one that's a mecca for lovers of a certain pre-cooked meat.
Our list also showcases a museum dedicated to a brand of sauce and another that honors a much-loved type of candy.

Spice up your travels with a visit to the Tabasco Museum on Avery Island, Louisiana, where the fiery sauce has been made by the McIlhenny family since 1868.
The Tabasco website reveals: "[Founder] Edmund McIlhenny grew his first commercial pepper crop in 1868. The next year, he sent out 658 bottles of sauce at one dollar apiece wholesale to grocers around the Gulf Coast, particularly in New Orleans.
"He labeled it 'Tabasco', a word of Mexican Indian origin believed to mean 'place where the soil is humid' or 'place of the coral or oyster shell'. McIlhenny secured a patent in 1870, and Tabasco Sauce began its journey to set the culinary world on fire."
The site's museum can be experienced as part of a "fan experience", which also includes a tour of the Pepper Greenhouse, Barrel Warehouse, the 170-acre Jungle Gardens and Tabasco Restaurant 1868.
Tickets cost $15.50 for adults, $12.50 for children (four and under are free) and $13.95 for seniors and veterans.
