30 inches high by 24 inches wide on stiff thin paper composite This will fit a standard size ready made poster, picture, or photo frame. Originals ship within 3 business days. Email me at firstname.lastname@example.org with any questions, etc. Spirit Dance is an ink painting with added acrylic details on a material called “artboard”. Artboard is a new painting substrate, made of acid free fiber composited with archival epoxy resin. It is thin like paper, but very stiff and sturdy, and resists mildew. I like the unique texture, wetting and absorption properties for fluid media painting.
