When you have the "collector gene" it is important to find all possible parts of a collection. With a collection of something like Winnie the Pooh -- which is endless -- there are collections within collections -- so if you're a collector AND OCD -- well... completing the nested collection is even more important.
Back in 1998 Disney started a collection of book-style Christmas ornaments produced by Hallmark. In 1998 I wasn't as -- shall we say -- "crazy" about finding each and every ornament. While, as you know, in 2008 when I became a Guinness World Record Holder -- all bets were off and my collecting OCD kicked in big time. Since then, I've been trying to finish the ornament book collection -- there were 12 in total.
Thanks to a wonderful person on Craigslist -- who had all 12 -- I was able to fill the voids in my collection. I am happy to say one nested collection is complete ... oh... and she had another 7 ornaments I didn't have.
Life is good!
