Here are the results of your search for Jumpin, the 3M Bookshelf Game. Jumpin is an uncredited design from 1964 in which players try to move their metal pawns to the back rows of the opposite side of the board. The first player to do that wins the game. The pawns move by jumping over other pawns - hence the name - as in Chinese Checkers, except the pawns may jump over any number of pawns in row.
