1990. October 24, 1990. Elkin effusively thanks the recipient for comments on his recent article and apparently for having sent him soap, a subject that had come up in the article: ". . . thank you most of all for those wonderful wrapped emulsifiers and alkali-reamed fats, those delicious sodium and potassium salts and acids. Man, if I had your job I'd have been World Soap Czar by now!" Signed by the author. Folded for mailing; else fine, with hand-addressed mailing envelope. [#015553] $95
