8.25x9.75" white unlined sheet contains mathematical equations and scientific computations written in Einstein's own hand. Below his work he has signed the page about 2" from bottom slightly off-center of page. Paper has a "Howard L..." water mark and was at one time pasted to another page, it has been removed and some paper and glue residue remains along top back margin. This residue shows through very slightly in a 1" square area in upper right corner but does not interfere w/any of Einstein's notes. Bottom right corner has a 3" crease and page has aged lightly. A very nice presentation piece. What notes pertain to is not known. As Einstein said, "The Whole Of Science Is Nothing More Than A Refinement Of Everyday Thinking." Fine to VF w/Exc. signature. Comes w/letter of authenticity from Hake's.
