What I like about this is it shows how Hardeen was really part of a Houdini franchise (without the financial component as Dash didn't pay a licence to Houdini, as far as we know). Franchising was not uncommon during the Golden Age of Magic. Harry Jansen became "Dante" when he was signed to head a Thurston franchise show. But those masters put their own names on the top of the bill -- "Thurston Presents..." Houdini kept the fact that Hardeen was a Houdini "franchise" a secret. Houdini's intent was to not spread his own name, but to control the market of imitators with his own. Indeed, Houdini and Hardeen were sometimes touted as rivals. However, this poster was a tell.
Did Houdini have other secret franchises? Dean Carnegie, on his blog Magic Detective, recently explored the story of Leonard Hicks aka The Great Leonard, a forgotten Houdini protege (franchisee?), who also performed the Milk Can.

One wonders if Miss Trixy's posters, like Hardeen's Milk Can poster, were variations on Houdini's own USD sheets. Unfortunately, no Miss Trixy posters, to my knowledge, have ever surfaced.
UPDATE: I just had a closer look at this poster and written on it is "of his famous brother Houdini." So this broadside/poster might date after Houdini's death, or the connection wasn't always so secret. (Unfortunately, there's no date on this.) One thing that's intriguing is this broadside is from the Keith's vaudeville circuit, which was the circuit Houdini played (Hardeen headlined on competitor circuits). Did Hardeen occasionally fill in for Houdini on Keith's where it was in their interest to play up the connection?
