Vintage glass bonbon or cracker stand, crystal clear elegant glass with Prelude pattern etch. This is probably Viking rather than the slightly earlier New Martinsville glass of the same etch and name, Viking generally has the smooth edge shapes. It's not marked or signed at all.
This measures 2 1/2" tall, 5 3/4" across the rim of the plate. It would be a sweet tiny cake stand for a special dessert or candy. Condition is excellent without damage or wear.
