More What's My Line?

Sometimes What's My Line? wasn't able to come up with really special, far out of the ordinary public figure as their Mystery Guest.  As a result, they had to go for the ordinary, everyday kind of household celebrity you normally get, hawking their latest American classic fine-art edifice.  And so, with apparently no one else to go to, they dragged out legendary architect Frank Lloyd Wright.  No doubt he was available because they'd finished shooting his appearances on Stop the Clock and The Price is Right.
