For your consideration is an original 24 June 1976 royal thank-you letter personally signed by King Simeon II of Bulgaria (b. 1937) and addressed to Mr. Joseph Nicklas of Glen Cove, Long Island, New York. Written on Simeons personal laid stationery bearing his crowned monogram, the letter opens with the handwritten salutation Dear Mr. Nicklas, followed by a typed message thanking him warmly for birthday wishes. Simeon writes that he has just returned from Stockholm, that he spent his birthday with Queen Margarita and their children, and that all were fortunately well. He concludes with renewed thanks and his sincerest greetings, followed by his large autograph Simeon R., the regal suffix R denoting Rex.

The letter is explicitly dated 24.6.76, only eight days after Simeons 39th birthday on 16 June 1976, and therefore represents a directly occasioned personal acknowledgment rather than a generic form response. The wording is unusually intimate for royal correspondence, combining travel information with a brief family update and recipient-specific handwritten address. The crowned monogram and bold regal autograph further emphasize Simeons continuing royal identity during his years of exile in Spain.

Simeon II became Tsar of Bulgaria in 1943 following the death of his father, Tsar Boris III, but was still a child when the monarchy was abolished in 1946 and the royal family was forced into exile. He later established his life in Spain while maintaining a substantial international correspondence network and continued to use the dynastic style reflected in the signature Simeon R. Decades later, he returned to Bulgaria and served as Prime Minister from 2001 to 2005, completing one of the most remarkable political careers of any twentieth-century European monarch.

Measuring approximately 6.5 by 8.75 inches, the letter remains highly presentable, with the crowned monogram, handwritten salutation, typed text, bold autograph, and date all clearly preserved. It is accompanied by a later Spanish envelope addressed to Joseph Nicklas, but that envelope is not contemporaneous with the 1976 letter and should be treated as an associated cover rather than the original mailing envelope. As a personally addressed birthday thank-you mentioning Stockholm, Queen Margarita, and Simeons children, the letter is a strong and unusually personal example of King Simeon IIs exile-period royal correspondence.
