Jackson Pollock Convergence Puzzle

I bought this from a thrift store as a challenge. I said "even if it's missing pieces, I won't notice!"

I did notice, but only because someone removed the majority of the edge pieces to, what, make this puzzle even more challenging?! Seriously, this has 7 edge pieces. The nice part is if you take away those 7 too, it really doesn't ruin the painting/puzzle at all. Anyways. I don't have the space to mount this so I've dismantled all of my hard work and anguish so that somebody else can have the experience. Best of luck :)

I don't even want to trade anything for this. If you're up for the challenge, it is all yours!
