So.... I will post the first airmail issues of Thailand from my collection here. Those of us with much older albums and catalogs may find these stamps listed under Siam. Siam is the name that was used as the name of Thailand before June 24, 1939, and again between September 8, 1945, and July 20, 1949. The Garuda is a common airmail theme among other Southeast Asia countries as well, like Cambodia and Indonesia.
