The card is a PSA 3, with centering pointed to the upper right corner on a card with a fabulous orange background.  Rickert is a tougher signature than many in the 1952 set (and generally) as he died fairly young, at age 57 in 1978 and missed the burgeoning show signing circuit that sprang up in the 1980's. It's signed in black and PSA/DNA has graded the autograph NM-MT 8, one of just eight signed examples between the red and black variations.
