Hi Serenity_Dreams
The first looks like it might be a Jackson Pollock.....but it's black and white, hard to tell.
The second is Andy Warhol, don't know what or where the photo came from
The third.....? Got me....looks like a Moai head from Easter Island.
That's just off the top of my head. Was it you I was telling that I teach art history to children?
Art is my back ground, so I'd love to dig around on this one
If you find out the exact pieces, let me know!
Have an awesome day!
