The Grand Duke’s Theater was located at 21 Baxter Street. On this map you’ll find it almost at the bottom, just right of center.
It was attached to a stale beer joint, one of most disreputable kind of saloons, where the dregs from beer barrels were sold.

It used to be a familiar sight to see the saloons of Baxter, Mott and Mulberry streets filled with these [homeless] boys. It was only a few years ago that they had their own theatre, “The Grand Duke’s Theatre,” at 21 Baxter street, in the cellar under a stale beer dive, where really clever performances were given of an imitative character, by a company of boys; and which, by the way, was the only theatre which for years defied the efforts of the authorities to collect the license. The admission fee was ten cents, and curiosity seekers came from all parts of the city to witness the really laughable and, in many cases, meritorious character-sketches given within its damp walls. It was subsequently broken up by the police.
