It was an art glass Christams for me. Here is another find, a 3x3x2 cube with label. It looks to me like it is a 1960s Mandruzzato sommerso based on the research I have done, but because these aren't signed the label is the only clue to the age and artist. It is consistent with the shape and colors of a Mandruzzato piece I saw on their website, but would appreciate any additional information and any estmate of the value. It is in perfect condition, no chips or scratches. Thanks.
