In honor of Teacher Appreciation Week, here are a few random school-themed cards. Remember these? From 1991 Skybox NBA, Upper Deck also participated in the “Stay In School” campaign at the same time. Packed chock-full of 1990’s design – teal! purple! swooshes! stars! – the set was part of a larger ‘Stay in School’ campaign through the NBA. Ah, 1990’s nostalgia at it’s finest.
