Did you ever go crazy looking for the manufacturer of a vintage piece? The hard part is trying to tell whether or not the piece in question is the real thing or a cheap imitation which has been recently manufactured! Years ago when Royal China, Scio, Taylor Smith-Taylor were producing pieces as give aways in detergents, little did they suspect that they would become collectible! Things to look for are naturally the shape of the piece, the Dimensions and the actual coloring of the pattern. When shopping it is best to carry a small reference book with you...but you can always go on "Gut Feel"!
