If you would like more information about Lotton glass, I started and maintain the collectors club for Lotton glass. You can find some good information on the club website
http://www.lottonglassclub.com Interestingly enough, Charles Lotton is coming to speak to our club members at just our 2nd ever annual club meeting. We are holding it in Cincinnati to run prior to and in conjunction with the Early Auction Company's April sale. I posted more information about the event in the proper forum and much more is available on the club website. You need not be a member to attend (and membership to my club is free, so there's no risk!)
