Okay, okay, if that one was too difficult, try this one.

The Art Instruction School was located in Minneapolis - 500 S. 4th Street. It went by the name "Federal School of Applied Cartooning" as well, back when it wanted people to draw the connection between artistic ability and getting a public job painting murals in Post Office lobbies, and the ads directed your correspondance to "The Federal Schools Building."

Which would be this.

It's still around; moved to the suburbs.
