A group devoted to the art of trees: free medium. Without trees the world would be dead and a place of disaster. With trees the world can tackle global warming. Hug a tree and you hug the earth, you hug yourself and your neighbors. Without trees, no love!

Without love, no trees.

A sequel to the mail art project SIGNS and STONES and TREES (of 1998).

Guido Vermeulen started this group. After his death the IUOMA members keep it alive with posting photos and drawings of TREES in memory of Guido.

Dear Guido,

I love trees!

Trees are so good to us, giving us oxygen to breathe, cleaning our water, providing shade in their life and shelter in their death.

They give us this paper, the pencil I write words with, and the envelope I painted.

Trees are magical, like all plants, magical little things that grow into magical big thins that are essential to so many of us other magical life forms in this amazing, magical universe.


When I am with trees, big and small, I wonder like a child.

I know the scientific explanations of their life cycles and the processes of their doings.

I have even listened to trees as recorded by a hydrophone as their cells thirsted for water.

Still, no amount of knowledge can evaporate the mist of awe and wonder I feel in the presence of trees.

Trees are our kindred.

They, too, are born to live. And born to die.

In between they are silent witnesses to the magic of the universe.

Happy Earth Day,

Speaking of Guido, I have one of his envelopes from several years ago that I've split to serve as an A&P. Any Tree Group members here like to participate in a "trees" A&P?

Guido would have loved it!

Thx, Guido used to see asemic writing in trees and he inspired me to explore Eco-Asemics: mysterious symbols and texts that occur in nature.

Love it DeVillo!!!! Super respect!
