This was one of the unpublished photos I shared during my presentation at the 2012 Official Houdini Seance (although this one went by a little quick). I think this is a quintessential photo of Houdini being challenged, and I'm thrilled to be able to share it here now.
Thank you, Jon.
UPDATE: This newspaper clipping from the Des Moines Register Nov. 23, 1924 shows that this migt have been an entirely different "bonfire" challenge than the Boy Scout challenge, which the caption says occurred in San Francisco.
