Largest Convention Hall and Theatre in the World, Atlantic City, NJ.

This old postcard is undated on the back.

On the front it says- Largest Convention Hall and Theatre in the World, Atlantic City, N.J.

The back notes-

All of Atlantic City's population, 66,000, could be seated in this building at one time in the auditorium. The largest home run Babe Ruth ever hit would stay inside the walls. Football is played on a full sized field indoors, and the building is indeed the Convention Capitol of the world.
