I somehow missed this last year when Microsoft was celebrating the 25th anniversary of the release of Solitaire. Areaware has teamed up with designer Susan Kare -- who's design is featured in the Solitaire computer game -- to release a pack of real playing cards with that iconic design.
I already had a Solitaire deck inspired by Microsoft's game from a few years back but this one is official and comes with a new design. Pretty neat. Now I own both!
