Q106 August, 2012   member 619  Mystery card I won the card below in the recent ESC Auction, and I’m curious as to what it could be... The card itself measures 108x80mm, and is made of white card-stock with black/blue fibres embedded throughout; there also appears to be a guideline present at the upper right. The representation of the five-millième Fourth Issue stamp appears to be an exact copy of the original stamp, down to all engraving lines. Any ideas?
