My brother has a sports collectible business done entirely through drop shippig. My online art company, EquinArt Creations (www.equinartcreations) drop ships about 60% of all artwork. It is possible to find a source. Try many web searches and use different search terms. Also look through places like Ebay - the other drop ship companies are selling there and you can see where the market is crowded and where there`s opportunity..
