I have a set of 6 glasses - all marked FRANCE with a 14 on the bottom. It is a little bit raised. They look clear, but when held at an angle, there is a blue tinge on one, pink on another, green on another and I think light orange on another. 2 are clear with no tinge of color. They have a contoured square design at the bottom. I have been looking for the maker for a while. Google is no help. They are just under 3-1/2 inches (9 cm) tall.
I attached a picture. Thank you for any help!
