TLS signed “Charles,” one page, 8 x 10, Kensington Palace letterhead, April 11, 1988. Charles writes to Mrs. Boehm. In part: “It is splendid to know you will be over here in May and extremely kind of you to arrange for the polo pony auction to benefit the Grooms Fund. What a really generous idea!… I shall actually be out of the country, but I do hope it is a great success.” Charles has also added the greeting and a sentiment, “With every best wish,” in his own hand. In fine condition, with a few light bends. R&R COA.
