DX
The Himalayan Kingdom of Sikkim was a super rare DX entity at one time. Only contacts made April 30, 1975, and before count for Sikkim. Contacts made May 1, 1975, and after, count as India (VU).1 It is worth noting that Gus Browning, W4BPD, operated from Sikkim in 1963 as a guest of AC3PT (Photo A) and in 1965 as AC3H (Photo B; AC3 was an unofficial prefix).
AC3PT was Palden Thondup Namgyal, the 12 and last Chogyal, or king, of Sikkim . He was a DX treat to the stalwart who could make it through the pileups. At the age of 6, he was a convent student; from 8 to 11, he studied to be ordained in. This wedding brought much attention to Sikkim.
