You'll notice this photo shows Houdini's piano (referred to as a "player piano" in a 1919 inventory). This is clearly not the same piano that was inside 278 last year. That piano was said to have been original to the house, so I suspect it actually belonged to the Bonannos. The piano was not among the items purchased by David Copperfield for his International Museum and Library of the Conjuring Arts in Las Vegas. Looks like that was the right call!
Below is the same room in 2017.
And before you ask, no, I don't yet know who bought Houdini's house. The house went under contract in January. We'll need to wait for the deal to close before we'll have a shot at finding out who the next owner of 278 will be. But the suspense is killing me!
