Issued by Monaco in 1966, this striking pair of stamps promotes the international campaign against drug abuse. The designs depict two human silhouettes trapped within a spider’s web, symbolizing the dangerous entanglement of addiction, while a syringe motif reinforces the anti-drug message. Printed in contrasting red (1.20 F) and green (0.80 F) color schemes, the stamps combine modern graphic design with strong social messaging typical of mid-20th-century public awareness issues. These stamps are notable for their symbolic artwork and are sought after by collectors specializing in social-cause, health-campaign, or thematic anti-drug philately.
