Thanks Alan/Sue,
I tried to remove the picture but I don't think I have the ability to do that, sorry about that. I have emailed the seller for more details as per your suggestion to whether there are markings below.
It doesn't really make a difference as I really like it but I do like to have a bit of history about the paperweight when displayed.
I will let you know if I get any further information back.
Thanks again
David
