I once saw a first edition, first printing copy of “And To Think That I Saw It On Mulberry Street” on ABE Books.
It sold for $11,000.
I’d say hang onto your old Dr Seuss books now! The ones missed by the thought police will be valuable when sanity returns.
It sold for $11,000.
I would guess that the decision to no longer publish this book has resulted in a significant increase in its value.
