ALS signed 'Jonas,' three pages, 7 x 10, December 27, 1964. Letter to an unidentified doctor, quite possibly Albert Sabin. In part, 'We've come to the end of another year and we are on the verge of one that may be one the most significant of a lengthening series of significant years. Neither of us would have had any way of predicting what would eventually surge from our association thus far, nor can we for tell the future still to come...The relationship between the N. F. and the Institute will once again demonstrate your prophetic sense as well as the soundness of your judgement. The solution of the polio problem, and the opening of new fields and new vistas in the course of so doing will be respected again and this time in an evermore...expanding way.' In fine condition, with small water spot to front page. RRAuction COA.
