*The Esperanto stamp collars issued in the Philippines in 1908 were produced in three colors: green, red, and blue. These stamp collars were created by the Filipina Esperanto Association as a fundraising initiative and were advertised in their magazine, Filipina Esperanto, during April and May of that year. The May advertisement specified that 500 copies were available, which is interpreted to mean 500 copies per color, totaling 1,500 across all three colors.
