THE WALKING DOLLS.
Harry Coleman of New Palace to Make Them a Fad.Harry Coleman's convict clad walking doll is going to have a lot of sisters and brothers some day for Mr. Coleman, the American ventriloquist, who is playing at the New Palace as one of the features of the current bill, is planning entering the manufacturing game soon to make these dolls for society girls. So many of these smart girls have raved over Coleman's walking doll and begged him to see the trick dummy to them that he has determined there is a big potential market for the contraptions. The dummy walks and even does a tango step or two as a close for a rattling good ventriloquial turn.
I just found that my doll is one of the Coleman doll. Thank for this info,,Very cool..especially the patent info.
