LOS ANGELES, CA.- Three letters and two pages of illustrations by Dr. Seuss will be auctioned by Nate D. Sanders Auctions on January 31, 2019. The letters and illustrations were directed to fellow author and long-time friend Mike McClintock.

The letters were written in 1957, which was a blockbuster year for Seuss (Theodor Geisel) as both The Cat in the Hat and How the Grinch Stole Christmas were published that year. Dr. Seuss enthusiastically wrote about the success of his new books and addressed the marketing potential of toys and games based on his characters. The lot comes from the estate of McClintock, who wrote the 1958 children’s book, A Fly Went By.

The first letter in the lot is dated May 19, 1957 and is written on Seuss’ personal stationery. It reads in part, “...you picked me off Madison Ave. with a manuscript that I was about to burn in my incinerator, because nobody would buy it. And you not only told me how to put Mulberry Street together properly...(as you did later with the 500 Hats)...I definitely am going into the by-product field this year. Because the CAT will reach 100,000 very shortly, and the print order on HOW THE GRINCH STOLE CHRISTMAS will in the first edition be over 50,000. And the Sat. Eve. Post will talk about this shortly in a profile that I wish to hell that you had written, / ANYHOW, if you want to talk toys and games, I'd rather talk to you than anyone I know…”

In the second letter, Seuss analyzes McClintock’s manuscript for A Fly Went By and also wrote “Cat Reading Game is a swell idea!''

Seuss’ last letter was written on December 5, 1957, in which he elaborates on game opportunities for The Cat in the Hat. It reads in part, “…The Hat Cat is doing a thousand a day. Latest printing brings print up to 200,000 in nine months...Which brings me to our toy-making-policy-planning... I believe that by fall...when my 'HAT-CAT COMES BACK' comes out, we'll have the biggest character that has ever come out of childrens' trade books...So, I think we're idiots if we don't think non-educationally, and start off on an opportunistic line......with a Cat-in-the-Hat Doll, Toy, put-together plastic, rag, fuzzy or whatever. But fast! / I'm riding a wave right now that may never again roll so high. So I think we oughta and gotta start in a different way than we planned. And get a Cat Character out as soon as we can. And THEN follow up with the game and the blocks and all the other things we want to do that make sense…”

The lot also includes two pages of several illustrations by Seuss.

Bidding for the lot begins at $3,500.
