After doing some research, it seems that the best places to search for bronze sculptures by Salvatore Melani is either through private sellers or through antique dealers such as prices4antiques.com or on ebay, which is seems to have the largest variety, selection, and the lowest prices, if you are looking to purchase them. The website artnet.com also lists auctions and sales of Melani as well as many other artists. Another site to check would be liveauctioneers.com as well as artquid.com.
