The late Microsoft co-founder Paul Allen, was an avid art collector and it's all going to auction. It's valued at 1 billion dollars.

What can you get? One of my favorites is Gustav Klimpt's Birch Trees. It inspired me for more than one of my collage musical tree paintings.

You could also grab Georgia O'Keeffe's White rose and works from Agnes Martin and Louise Bourgeois.

There doesn't seem to be a recession when it comes to major collectors. This is expected to sell for the highest ever in art-auction history.
