Davestar,
Ahh.. two parents and their kid getting ready to take out the rebellion!
Seriously, those are nice models. Why put in all that work and use them as piñatas? My guess is that the one in the center was the original and the two on either side are scaled up versions?
BTW I like the link you provided, the close up of the smaller AT-AT, and especially the three headed dragon. Looks good.
Have and great week!
