Mike Lawrence

Mike Lawrence held announcing duties on the Shopper's Bazaar pilot in 1973, the first to do so on what eventually became Wheel of Fortune. He is also the most unknown of the American franchise's on-air staff due to fans not having any footage, photos, or audio of him on said pilot.

As a result, it is not known which Mike Lawrence he is. For reference, Wikipedia lists seven people by that name (one born in 1990), while the Internet Movie Database lists 11 under "Mike" and 22 under "Michael".
