Henry:
The key label is the Bertil Vallien one. He's one of the biggest names in glass, so I won't say too much. You can use the search function on the GMB to find out more or simply Google him. I think this is a fairly early piece.
The other label is a retailer's label for Ilums Bolighusi, I think. The piece probably made at Afors (Sweden) and sold as Afors or Boda. More likely Boda, would be my guess.
