Here we have all 72 models (3 calendars x 24 days each) laid out on a towel-covered table. The pics that follow show the models and parts in various combinations. Click each image for a larger view (on Flickr).
Finally, we have plenty of spare parts. Whenever there is a smaller part such as a 1×1 round plate or tile, you will often see one or two extras included along with it… I’ve shown you the extras for each day as we’ve gone along, but here they all are collected together.
