Each individual piece has a four digit identifying number ranging from #0000-#9999.


Each of the characters are represented by the first two digits of the issued number. This collection is laid out on to 100 different, carefully selected backgrounds. These are represented by the last two digits of the identifier. The background colours will always remain in the same order throughout the collection.


All colouring (and of course drawing) was done manually. The colour selection is based on the 100 backgrounds, plus the original ‘Reptilian Green’ to make 101 available colour options. No two pieces are the same, and each piece can be easily found using the indexed numbering system (once the item is released).
