Mr. Marx (not the one you are thinking of) drove a semi for a truck company and liked it so much that he requested this monument. Definitely unique in design.

This monument is an impressive collection of marble and granite.

Notice the railway car that is running into a tunnel at the base of the tree. This is a monument to the man who designed the first Post Office mail car. It was designed to collect, sort, and deliver mail with postal clerks working on it as the train sped on its way. High tech in its day.
