Looking for opinions/appraisal on a rare medical book in my collection. I have what appears to be a 1st edition, 2nd state 1892 copy of The Principles and Practice of Medicine by William Osler in very good condition. It also comes with the original 1892 publisher/bookseller receipt and provenance tied to Dr. William A. Peck, former dean of Washington University Medical School.

I’m curious how significant the provenance and original receipt are to collectors, and what a realistic appraisal or auction estimate might be. Would appreciate any opinions from collectors, dealers, or anyone familiar with rare medical books.
