Reposting my artwork to blogs, Tumblr, Google+, Pinterest or anywhere else is not allowed without my permission. My permission is usually not hard to get if you ask first. Using the 'share' buttons located at the bottom of my pages is fine.
Interior designers and corporate art buyers for large-scale projects can buy my prints at trade prices at DesignerPrints.com. You can also contact me here for information on commissioned custom art for your project.
