Not exactly what I'd call a "collection," but here's some things I've bought/received over the years. Enjoy! (PS- apologies for the awful photo quality, my phone camera is really bad)
The pin I got at One More Disney Day, Leap Day 2012. I loved these 24 hour events Disney did back in the day.
Posters from the 2016 Disney Attractions Poster Calendar. I especially like the Mystic Manor one.
Probably my favorite collectable; 20,000 Leagues Under The Sea pin from the Remember When pin collection. It's made with actual metal from the ride, plus only 250 were sold! COOL!
And my favorite photo; small me on my first ride on SheiKra, circa 2010 (that's the itty-bitty version of yours truly, far left). I was terrified. My dad (directly next to me) was having the time of his life. lol
