This game is a copy of Gottlieb's 1972 'Grand Slam' except the kick-out holes score 3000 points instead of 1000 points. We previously showed a date of 1972 for this game. The manufacturer plate affixed to the upper playfield apron indicates the Director General of Security (Police) Authorization date of Apr-23-1973. However, pictured in this listing is the Government Authorization letter (attached to the inside of the backbox door) which is from the same authorizing entity and is dated May-4-1973. It is safe to date this game as 1973. During the dictatorship of General Franco not only they could not import pinballs, they also banned casinos, bingo, and slot machines. Until Spain became a democracy, pinballs manufactured there needed a special authorization from the Ministry of Interior which was the department responsible for security and public order, and then authorization from the aforementioned Department of Security. With Spain's democracy and the legalization of gambling, pinball machines no longer needed authorization from the Department of Security. Only the Ministry of Industry authorization was required.
