Born Giuseppe Melchiorre Sarto in 1835, Pius X served as pope from 1903 until his death in 1914. Known for his conservative, anti-modernist philosophies, he became, in 1954, the first pope to be elevated to sainthood since Pius V in 1712. Handwritten endorsement, in Latin, signed “Pius PP X,” dated in his hand “27 Feb. 1905,” at the bottom of an ALS, in French, dated February 17, 1905, signed “Philippe Eveche d’Evreux,” on an 8.5 x 11 sheet. Pius pens a four line endorsement in the lower left corner, signing underneath. Central horizontal and vertical fold, uniform toning, a bit heavier at edges, some small edge tears, and a few light creases, otherwise fine condition. An interesting and less-seen format for any Pope. RRAuction COA.
