Welcome to the board - we are a very friendly lot so no need to worry!
There is an excellent little booklet called "The story of St Clair Glass" author
Jane Ann Rice who was one of Paul's sisters. This tells the story of the
St Clair family with plenty of archive pictures including three of Paul.
In the original booklet the glass was photographed in colour. This version is
very hard to find. However there is a photocopied version which occasionally
appears on E-bay with all B&W photos.
There are also many references to St Clair glass in Jean Melvins book "American
glass paperweights and their makers" This is out of print but a quick search on
abebooks dot com showed 35 copies available worldwide.
Hope this helps
