Started in 2004 - three cards away from complete 1915 set. Wow should I apologize for starting you off on the journey Steven? 
 
I had been out of baseball cards for decades and had just recently started looking at what out there and prices when I happened to see that Topps had released the 2004 Cracker Jack.  Until they made that set I had never heard of the 1914/14 Cracker Jack set.  One look on eBay and I started to pick them up whenever I could.  I certainly have met some great CJ collectors along the way!
