A diorama is a replica of a scene, typically a three-dimensional model either full-sized or miniature. Sometimes it is enclosed in a glass showcase for a museum. Dioramas are often built by hobbyists as part of related hobbies such as military vehicle modeling, miniature figure modeling, or aircraft modeling.[citation needed]
In the United States around 1950 and onward, natural history dioramas in museums became less fashionable, leading to many being removed, dismantled, or destroyed.[1]
