| 正面描述 | Draped bust of Princess Chulabhorn Walailak facing half-left, wearing academic mortarboard with tassel. A curved Thai-script legend encircles the effigy along the rim, identifying her full royal title. The portrait is rendered in moderate relief against a flat field, capturing the Princess in academic regalia befitting her scientific distinction. |

Issued to mark Thailand's participation in the international commemoration of the centenary of Albert Einstein's birth — an event coordinated across dozens of nations in 1979, though Thailand's release came several years later under the Buddhist Era calendar year 2529. The delay was not unusual; Thailand issued numerous science and culture commemoratives through the mid-1980s tied to UNESCO-affiliated programs on staggered schedules.
