Most of My Items Are Vintage. All of My Items are Being Sold As Is, As Seen, As Found. I lightly Wipe The Items, But Leave The Cleaning Up to The New Owner as I Don't Want To Damage Any Items!! I Try & Describe The Items, As Best as Possible. Vintage Items May Show Wear, Have Some Lite Scratches or Scuffs. Ebay Charges State Tax. Aberdeen is in Maryland. Cup does not have the word Maryland on it. The Proving Ground is related to the US Military.
