Beanie is the name for two distinct types of cap or hat The name
"beanie" probably comes from the early-20th century slang term
"bean," meaning "head".  The beanie cap is typically made of
wool felt, and was popular amongst school age boys from the
1920s to the early 1940s. Beanies are brimless and either have a
small embellished visor or, more commonly, no visor at all.  One
popular style of the beanie during the early half of the
twentieth century was a skullcap made of four or six felt panels
sewn together to form the cap. The panels were often composed of
two or more different colors to make them novel. This type of
beanie was also very popular with college fraternities as they
would often incorporate school colors into the beanie.  Another
style of beanie was a formed and pressed wool hat with a flipped
up brim that formed a band around the bottom of the cap. The
band would often have a decorative repeating zig-zag or
scalloped pattern cut around the edge. It was also quite common
for schoolboys to adorn
