"Dear Dr. Eggert,
It has recently been brought to our attention by Dr. Spencer that you are desirous of obtaining a copy of Wall's "History of Color Photography", but that you have been unable to obtain one on the Continent. I understand from Dr. Spencer that he also has been unable to find a copy of this book in England.
Upon receipt of Dr. Spencer's letter I inquired of the librarian about the possibility of our having an additional copy of Wall's "History of Photography" which we might send to you. I find here is a copy, and I am very happy to be able to present it to you with the compliments of the Kodak Research Laboratory in the hope that you will find it useful in connection with the work at your Institut.
With kindest personal regards,

That's pretty cool! I love when I get books like that. So far, my best one on photography is merely stamps from the 3M library...
For up from the ashes, up from the ashes, grow the roses of success!
