Actually am only missing the very first one now - Series 1 Basic R - butat the time I took this photo, I had just opened up Series 32, and the one from Series 16 I acquired after posting this shot looking for the two am missing...
And speaking of Series 32, it is soooo cool that for the 20th Anniversary of Medicom Toy and the 15th Anniversary of Bearbrick, the letters spelling out Bearbrick are placed on the back!!!
