US Scott #Q12 Mint, No Hinge. Expertly Regummed

US Scott #Q12 Mint, No Hinge. I purchased this stamp in 2010 from the Ebay dealer 'georgetownlaw' as being "Regummed". The re-gumming appears to have been done by an expert. Please see photos for perfs and centering. From my personal collection of over 55 years which I am now selling. US Shipping Only. This stamp will be mailed in a rigid, photo grade mailer with insurance for maximum protection.
