Dr Seuss Banned books all 6 complete set vintage older editions plus 13 more

Dr. Seuss, banned All 6 books no longer in print complete set plus 13 other vintage Dr. Seuss collectible books. These are old books( and yes they smell old) I’m not sure some of them might be first additions. If you look at the back of the books on beyond zebra, if I ran the zoo, Mcelligots pool, and scrambled eggs, the back cover are the old vintage. You can look at the copyright also I’m not sure how you determine the addition, but they all are definitely old. That’s a nice set for the price. Most of the books have an inscription in the front however they are not ex library books, ripped up, drawn in,
