ALBERT EINSTEIN - SIGNED OUT OF MY LATER YEARS (PHILOSOPHICAL LIBRARY, NEW YORK) - ALBERT EINSTEIN - SIGNED OUT OF MY LATER YEARS (PHILOSOPHICAL LIBRARY, NEW YORK) Signature: Signed clearly on the title page by Albert Einstein, who has also written the scientific formula ”E = mc²” beneath his signature in his own hand. Description: Octavo, dark blue cloth boards with gilt titling to the spine and upper cover, showing moderate handling wear commensurate with age, including minor edge rubbing and light surface marks. The interior pages are clean and well preserved, with the autograph prominently placed on the printed title page. The ink remains legible and stable, with balanced tonal contrast against the paper. The presentation is visually striking due to the presence of both the full Albert Einstein signature and the handwritten formula, creating a strong display quality for collectors.
