Yes, I bought a complete OS6 set simply because I am a WP collector and fan. The price, however, is outrageous!
No, this is absolutely nothing like trading cards when I was a kid. Back then, prices were reasonable, and one didn't have to spend the equivalent of a major utility bill.
Just imagine what "Topps Goes to the Movies" - a 90 card set, mind - is going to cost - with all of the extra "bonus" ludlows, sketches, etc.. Start saving up your pennies, boys and girls!
