[quote name=\'bradhig\' post=\'250727\' date=\'Nov 11 2010, 04:38 PM\']I have seen photos of Alex Trebek standing by the dice table with big light up numbers behind him like the ones used on the 1987 version. When did the 1970s version have big numbers and what did they look like compare to the later version?[/quote]
Most of the original version of the show from 1974 to 1976 didn't have any of that "column" stuff going on, you simply knocked out numbers and turned over prizes (or half-prizes, in the case of the car) that were yours if you won the game. (This was on a slightly smaller board than the Big Numbers, with the numbers still arranged in two rows.)
The Big Numbers was played against the board you see in the picture, hence the name.
The version we tend to see clips from ran from 1978 to 1980.
