Issued by Honduras in 1975, this airmail stamp promotes forest protection under COHDEFOR (Corporación Hondureña de Desarrollo Forestal). The design features bold geometric landscapes and the COHDEFOR emblem, combined with the environmental message “Protege los Bosques – El Humo y la Ceniza No Se Exportan” (“Protect the Forests – Smoke and Ash Are Not Exported”). Its striking modernist artwork reflects Honduras’ 1970s conservation efforts and remains a popular thematic item for environmental, forestry, and Latin American postal history collectors. Denominated at L.0.70, it was printed by Lito Maia, Porto, Portugal.
