Not sure I like the word abandonment. I prefer gifting. The object is to leave random bits of art work in public places for others to find and hopefully appreciate. See more here https://www.facebook.com/groups/ArtAbandonment/
I have left a few items but have no idea if anyone took them home or threw them away. One was in a park near my home and I know it disappeared. If the grounds keeper found it I hope he took it home rather than throwing it away. Oh well, that is part of the game.
Hen and Chickens
I may take this one to hide in
my sister in law's house this week.
I want to gift this one in a coffee shop
My favorite. I may keep him for a while.
Perhaps in a garden shop
And I think these two are for my grand kids.
