Most museums specialize in one area–science or art, for example–and then there are a few museums that focus on something much more specific, like cockroach dioramas. We’ve rounded up a few of America’s most specific museums, displaying fascinating collections of artifacts ranging from the aforementioned cockroach art to mustard and kazoos.

Cockroach Hall of Fame

Where: Plano, Texas
What You’ll Find Here: Pest control specialist Michael Bohdan curates a collection of dozens of cockroaches dressed up and displayed as various historical figures and luminaries, including “Liberoachi” and “David Letteroach.” In addition to the dead bug dioramas, the museum houses a group of Madagascar hissing cockroaches that are very much alive. The Plano Chamber of Commerce, at first opposed to publicizing the museum, has finally embraced the quirky landmark as an integral part of the community.
Don’t Miss: The Statue of Liberty clutching a cockroach instead of a torch–if this doesn’t make you feel patriotic, then nothing will.

National Mustard Museum
Where: Middleton, Wisconsin
What You’ll Find Here: Mustard–5,300 varieties of it, to be exact, from all 50 states and 60 countries. This popular museum has the world’s largest collection of mustards, many of which are displayed on the Great Wall of Mustard. There’s also an impressive collection of mustard memorabilia, from vintage mustard pots to a French’s Yellow Mustard mascot uniform. Looking for mustard-themed performance art? Head to the Mustardpiece theater to check out a musical, like The Sound of Mustard.
Don’t Miss: The Tasting Bar, located in the museum gift shop, allows visitors to sample from hundreds of different flavors.

Leila’s Hair Museum
Where: Independence, Missouri
What You’ll Find Here: Vintage hair art, dating back as far as the 17th century. Victorian families often wove family members’ hair into elaborate works of art. Curator and owner Leila Cohoon started collecting hair art nearly four decades ago, and has since grown her collection to 159 hair wreaths (many in their original frames) and over 2000 pieces of jewelry.
Don’t Miss: Hair wreaths from two sisters whose heads were shaved when they entered a convent.

Lunch Box Museum
Where: Columbus, Georgia
What You’ll Find Here: Between 1951 and 1985, only 450 distinctive designs of metal lunch boxes were released. Allen Woodall Jr. has collected every single one of them, along with other unlicensed metal lunch pails that are not technically considered collectibles, but fascinating nonetheless. The Lunch Box Museum, in total, houses 3,500 specimens (complete with matching thermoses), some of which are available for sale or trade.
Don’t Miss: The original painting of David Hasselhoff that became a “Knight Rider” lunchbox.

Kazoo Museum

Where: Beaufort, South Carolina
What You’ll Find Here: Housed in the Kazoobie Kazoo Factory (naturally), the Kazoo Museum displays nearly 200 kazoos and kazoo memorabilia, honoring one of the most rarely honored instruments. Visitors can view some of the oldest kazoos in the world, kazoos shaped like cartoon characters, and the hard-rocking electric kazoo.
Don’t Miss: The museum’s collection of kazoo band records and sheet music is a must-see for kazoo music fans and people who had no idea kazoo bands existed.
