Bee is a pen name of Lubbers (Jerry Bails' Who's Who).
Hart is credited on this feature by Jerry Bails' Who's Who, and heads in 3/4 backview are identical to his stories in Black Fury Comics (Charlton), as are the movement of hands, and also the big eyed youngster, Kip.
This may be a hitherto unpublished K-9 story, as it does not appear to be reprinted from a Chesler / Dynamic comic.
Originally feature indexed as Masked Blackjack, but it is only the alias of the suspect in this apparently true story. Gay Desperado renamed Masked Blackjack.
