In 2015 Card-Shark (Christian Schenk) designed two special souvenir decks of cards for the attendees of the 4F Convention (Fechter's Finger Flicking Frolic) which is the "Original Close-Up Magic Convention" that was held on April 22-25, 2015, in Batavia, New York.

The two decks were identical except that one had red backs and the other had green backs. We were able to get a few of each for all the serious card collectors.

Manufactured and designed by Card-Shark Germany. Printed by the US Playing Card Co. on their air-cushion Poker size stock. Very limited quantity.
