Partial handwritten manuscript in German, penned on an off-white 8.5 x 5 sheet by Albert Einstein, unsigned, no date but circa late 1928-early 1929. Lower portion of an unpublished paper dealing with the Unified Field Theory and Hamilton's Principle. In early 1929, Einstein published two articles on the Unified Field Theory in the session reports of the Prussian Academy of Sciences, which at the time made international news. As in the two published articles, Einstein acknowledges the help of Polish mathematician Hermann Muntz, "for the solution to this dilemma I thank Mr. Muntz, for his remarks according Cauchy's theorem." The manuscript also features two mathematical formulas. In fine condition, with light creasing to the lower left corner, missing lower right corner tip, and a small chip to the top.
