Nice to see the Yahoo! group migrating here. Obviously it was my old stomping grounds but to be honest, I was left feeling pretty unwelcome for a variety of reasons.
If and when it comes up, you must get Dumbo, Schnoogans, the photos do not do the beauty of the piece or its lighting justice. I would argue it's the most beautiful of all the Olzsewskis pieces to date.
As for the right table size, I have Main Street on a six foot folding table with no cover (starving college student). I probably will either get a four foot table and just put them end to end or see about a 10 foot table. I do not relish having to move a fully assembled Main Street though.
