These theory11 playing cards created in partnership with actor Neil Patrick Harris are delicate, intricate and beautiful. Harris personally art directed every aspect of these cards and its designs — a process which took over a year. Featuring gilded details inside and out, the cards are also a limited edition (RED) product, with proceeds helping the fight to end AIDS. Each deck sold will provide three days of life-saving HIV medication to someone in need. Head over to theory11 to purchase a pack for yourself or as a gift this holiday season; each deck retails for $10 USD.
