I'll chime in here.
This piece does not strike me as an AVEM piece, but something more generic....
I do not think of this type of glass as Tutti Frutti. To me Tutti Frutti, as done by AVEM contains much larger and more defined fragments of canes, ribbon and latticino. I also do not associate the use of streaks of solid color glass in a Tutti Frutti piece.
To me, Tutti Frutti is an artistic conglomeration of canes and latticino suspended in clear glass, which may or may not be over a colored vessel, but not containing "smears" of solid color. My understanding is that it is a name applied to a technique developed by Dino Martens at AVEM, although I feel the term has been widely applied to even remotely similar pieces through the years, for lack of a better descriptive term to apply to remotely similar work.
Most Tutti Frutti pieces I have seen are not very large, and the ones that are AVEM Tutti Frutti and are large are typically associated with high price tags to go with the size.
This is a link to an AVEM Tutti Frutti piece. This piece is a little larger than most at around 6 inches tall. You see a lot of Toothpick holders and such in what I see as authentic AVEM Tutti Frutti..... http://antiquehelper.rfcsystems.com/Full/715/61715.jpg
Hope this helps.... Someone else can certainly correct me if my understanding is flawed.
