Issued in 1977 by the Republic of Turkey (Türkiye Cumhuriyeti), this 250 kuruş postage stamp promotes environmental conservation with the message “Ormanı Koruyunuz – Ağaç Dikiniz” (“Protect the Forest – Plant Trees”). The design features a stylized green triangle representing a tree, with roots extending below — a powerful symbol of growth and sustainability. The minimalist graphic style and bold use of green emphasize ecological awareness during the global rise of environmental movements in the 1970s. Printed by the Türk Tarih Kurumu Basımevi, this issue highlights Turkey’s early postal advocacy for reforestation and preservation of natural resources.
