Donruss Bomb Squad was a 6-card insert into 1995 Donruss. Back in those days, some of the card manufacturers used to randomly place "hot packs". These would be individual packs that had something special in them. I don't remember if the card companies advertised this practice or if I learned about it from Beckett Magazine.
Anyway, one day in 1995 I bought a couple packs of Donruss and all six of the Donruss Bomb Squad were included. A so-called hot pack! I never saw another one. The cards featured the top six home run hitters from each league of the 1993 season.
Card 1 of 6 - Matt Williams (43) and Ken Griffey (40)
Card 2 of 6 - Jeff Bagwell (39) and Frank Thomas (36)
Card 3 of 6 - Barry Bonds (37) and Albert Belle (36)
Card 4 of 6 - Fred McGriff (34) and Jose Canseco (31)
Card 5 of 6 - Andres Galarraga (31) and Cecil Fielder (28)
Card 6 of 6 - Kevin Mitchell (30) and Joe Carter (27)
