Please Read Carefully Before Bidding: I strive to find unique and difficult to find pieces that I believe will capture the attention of collectors. I spend a great deal of time traveling, talking with people, sitting at auctions and waiting in line at estate sales to find these pieces. Some of the items are "farm fresh" and some I have had in my possession for years and time to let others enjoy. Please make sure this item is what you want before bidding. If you would like different pictures or have concerns about damage, on whether it is repainted or repaired ask before bidding. If I can find out, I will. These are antiques so expect them not to be "perfect".
