What is a safe way to remove the stickers or price tags without damaging the artist signatures?
The signature and other Limited Edition markings are fired onto the bottom of the piece of glass for permanence just like the decoration. It won’t damage any of the markings to remove the price tag. Just use warm soapy water to remove it and it should be fine. Note that some collectors like to leave the price tags on their pieces so that they have some way of keeping track of how much they paid.
