The Flashback 3 series is the fourth GPK set to contain Sketch cards numbering 1/1 (one-of-a-kind, found within hobby or retail boxes). Nine GPK artists worked on the Sketch cards for this release; veteran artist Tom Bunk; next-generation artists Brent Engstrom, Fred Wheaton, Layron Dejarnette, Mark Pingitore, Joe Simko, Colin Walton, Jeff Zapata and Neil Camera. Besides the sketch cards located within the boxes, the artists were also given 10 blank sketch 'Return' cards from the Topps company, and once approved, could be kept, sold or auctioned — these sketch cards are often more highly detailed.
