The first is found in the trailer for Hocus Pocus 2. Looks like the characters visit a magic shop and there's a Houdini poster on the wall. This is a reproduction of his "Do Spirits Return?" poster used during his second 3 Shows in One tour. Prints are widely available online.
The next one shows up in episode 4 of the Marvel series She-Hulk: Attorney at Law. You can see a Houdini "Buried Alive" poster on the wall of the "Mystic Castle" (a thinly disguised Magic Castle). Quite a few golden age posters can be glimpsed in this episode. Buried Alive was also a poster made for his second 3 Shows in One tour.
You know, I continue to hear rumors of some kind of Houdini project active inside Disney. I have no idea what this is. But, hey, I'm right down the street! Just saying...
Thanks to George Lescay for the alert.
