Look in the Rider-Waite history forum- Fulgour posted links to it on several occasions.
I have types it out for you- there is a small copy of it in Kaplan Tarot Encyclopedia Volume 111.

Dear Mr Steglitz
I wonder how you are!!- I want some money for Christmas-! I wonder if you got Mrs Busches money for the "Moon"?- Can you send it to me?
I have 8 or 9 new things- I am sending over next week- you will like them I think-Perhaps a few people may care for one or two- they are careful & nice colour- & larger than any except the Wave one.--I hope you are doing well & the Little Galleries are still there! - I've just finished a big job for little cash! a set of designs for a pack of Tarot cards 80 designs- I shall send some over- of the original drawings as some people may like them! - I will send you a pack- (printed in colour by Lithography)-(probably very badly!) as soon as they are ready- by Dec 1.- I think-
With good wishes to you and Mrs Steglitz & the Secession all of it- from yours sincerely.. Pamela Colman Smith
Hope this helps! (fond of exclaimation marks was she!!!!) ~Rosanne
