ANY REASONABLE OFFERS WILL BE CONSIDERED!
The items I find are farm auctions, household auctions, etc. I will give you a description, to the best of my knowledge, regarding age and information found on those unique pieces. All sales are final, so I ask that you zoom over the pictures for a close view of them since I do NOT accept returns. If have any additional questions, please feel free to contact me. If, after you receive item, it does not meet your expectations, please contact me. Also worth mentioning, since many of my items are big and bulky, I do recycle cardboard. Also, many do not realize that I live in north central Wisconsin and my shipping charges are a little more costly than if I lived in Central United States. My shipping is based on ebay's estimator calculator.
