Fred sends us some photos and says, "You could just imagine Houdini walking down these stairs with his mother on his arm, all puffy chest a proud son."
"How my heart warmed to see the various friends and relatives kneel and pay homage to my mother, every inch a queen, as she sat enthroned in her heavily carved and gilded chair." - Houdini
While no photos of this famous reception survive (to my knowledge), it has been depicted in two Houdini biopics, The Great Houdinis (1976) and the Houdini Miniseries (2014).
Here's an image from Fred's collection capturing the real Harry, Mama, and Bess at this very time.
