Acquired this fun, massive green and yellow vase today. It's Italian, I think, and fairly new. I'm assuming 10-20 years old. It came with a folded cardboard "guaranzia" (all in Italian, without name of producer). The original store price tag, which I removed, said $65. The producer's label is torn and worn, but appears to begin with "IM" and might be 4 letters. I'm tempted to use the vase, but seems like it would be a nightmare to clean. Anyone know who made it, where and when?
