Higher grades have just lt. margin/corner tip wear. Our breakdown is as follows: Good 6, VG 17, VG/Exc. 27, Exc. 31, Exc./NM 10, NM 17. This set was originally planned, in 1951, as a 180-card series but the artwork for cards 109-144 was lost. Many years later the art for cards 145-180 was found and in 1980 these cards were finally printed. As a bonus, this lot includes that modern day printing of those 36 cards in Mint condition.
