I'll Buy That! was a game show hosted by Mike Wallace back in the days when Mike Wallace sometimes hosted game shows. The show debuted June 13, 1953 and lasted a few months into 1954. Home viewers would send in items they wished to sell and a celebrity panel headed by Vanessa Brown and Hans Conreid would attempt to guess what each item was. Every time they made a wrong guess, the "selling price" would go up.
How was it? A fine question. There don't seem to be many (any?) episodes around. But its cancellation and the failure of a few other attempts got Wallace out of the game show hosting and into news work. So that's something.
