The 1921 E121 Herpolsheimer Co issue remains the more rare of all the E121 and W575-1 related issues of the early 1920s. Just one example of each known card is known to exist all found together at the same time. Each of the cards were in excellent condition but each contained pencil writing on the reverse that reduced the technical grade. This example of Giants outfielder George Burns has been graded GOOD 30 by SGC due to the aforementioned writing. Regardless it is not the technical grade of a 1921 Herpolsheimer that is important it is it's incredible rarity as each card is currently the only example known.
