1970–2020 Earth Day

Earth Day

First held in 1970, Earth Day is an annual event on April 22 to demonstrate support for environmental protection.

SMA: The Program Lifecycle Company celebrated Earth Day at its weekly Town Hall on April 24, 2024, and featured a Stamp Talk showcasing the stamps in this collection. The Earth Day wallpaper was created by Patricia Ventura Parra of SMA’s Creative team, and the collection was supported by SMA.
