Alex has a website featuring his artwork and that sells cards that he has created. (The cards are also available for sale at VisArts in Rockville.) The cards feature his artwork and can be blank or include a quotation on the inside.
I particularly like this featured quote: "Disability is not a brave struggle or 'courage in the face of adversity.' Disability is an art. It's an ingenious way to live." —Neil Marcus
Furthermore, if you are interested in learning how Alex and his mother Diana set up Alex's business, you can read her blog on the subject. Contact Diana with any questions at firstname.lastname@example.org.
