As far as I know I have finally completed the 2010 Ambassador Halloween pin set! I started looking for these pins in July 2012 after my younger brother bought me my first Disney pin. A waving, smiling, black and white Steamboat Willie! I still have it too! I acquired the first pin of the series I think in 2014 and it was Donald Duck. Here is what the set looks like together. Please let me know if this is not the complete set!
