The 2015 Series 1 is the tenth GPK set to contain Sketch Cards numbering 1/1 (one-of-a-kind), found within hobby boxes (inserted 1:? packs) or retail boxes (inserted 1:232 packs). Die-Cut Sketch cards can be found within hobby boxes (inserted 1:? packs) or within hobby collector edition boxes (inserted 1:143). Several GPK artists worked on the Sketch cards for this release, standard sketch cards: Chenduz, Brent Engstrom, Dustin Graham, Joe Simko, Neil Camera, Layron DeJarnette, Mark Pingitore, Jeff Zapata, Steve Potter, Fred Wheaton and Pat Barrett. Besides the sketch cards located within the boxes, the artists were given ten blank sketch card 'returns' from the Topps company, and once approved, could be kept, sold or auctioned -- these sketch cards are often more highly detailed and go for a higher price.
