Hi Springhead, and welcome to the board. Thank you for sharing your images with us, I'm sure they will be useful.
We do have a dedicated album on our GlassGallery for Murano Glass labels, to which you are welcome to add your images as well. As GlassGallery is part of the board we know that images there will remain as a reference source in perpetuity.
If you'd like to take a look, you'll find the gallery here: http://glassgallery.yobunny.org.uk/
and we also have albums for non-Murano glass labels, known fake signatures, as well as copies of old adverts, and individual research collections. Your input into any of the albums would be welcomed.
