This watercolor is from a small group of watercolor paintings on 9/11. Isa and her husband watched in disbelief and terror, when thousands were murdered as each tower collapsed, from their roof in their Chelsea loft. Like all of their fellow New Yorkers, and the world, they felt so helpless and heartbroken. Those memories, and the images, are impossible to relinquish, but Isa did manage a series from that day. Do you remember how blue the sky was?
