This is the call up box in my kitchen. Which seems to be as old as my apartment building itself - and the apartment building was built in 1927.
Note the wires, which have been spliced together many times. Note also the lack of key pad, denoting that when you pick up the ear piece, you are automatically connected to the operator - or in my case, the doorman. Did you hear me mention ear piece? Yeah, because you pick up the little circle guy, and hold it to your ear while speaking into the round voice receiver in the center of the box. Like in really old movies.
(Everything about our apartment is awesome. Did I mention that there are 5 closets in the place? Yeah. It's great. And the move went well. Thanks for asking.)
