Issued by Saarland during the post-World War II period, this striking 15 Francs stamp promotes forest fire prevention with the bold warning “Verhütet Waldbrände!” (“Prevent Forest Fires!”). The dramatic red background and silhouetted burnt trees reflect early environmental awareness and public safety messaging in European postal design. Produced when Saarland operated under French economic influence, the franc denomination adds historical significance. Its strong propaganda-style typography makes it a visually powerful thematic issue. A desirable piece for collectors of environmental, forestry, and occupation-era European philately.
