Books?

Hi everyone , I am a big fan of Keith’s work. Ever since I was younger (M26) I had a huge appreciation for his work and messaging.

I am interested in buying books that showcase his work throughout the years and wanted to ask if anyone knows which books or sellers out there benefit the estate / organization. There’s so many options and I want to be able to purchase directly from a place that would benefit the work that the Keith Haring Organization does today.

Not sure if this is too niche of a question but any insight will be super appreciated. Thank you!
