Since the hand inscribed marks varied greatly from piece to piece and decade to decade, signatures can easily be faked. There are indeed unscrupulous sellers who have taken unsigned antique glass in similar styles to those Tiffany made and marked them with a fake signature. Studying the colors and styles of genuine Tiffany glass, along with examining authentic Tiffany marks, are excellent ways to learn to recognize authentic pieces. The more you study the nuances, the easier it will become. This mark, specifically the L.C.T., has been faked many times by those trying to fool unsuspecting buyers into thinking another type of iridescent glass is actually Tiffany. It is wise to examine the piece closely in all aspects before making a purchase.
