I have seen those mannequins (and some even larger) both in Panama and in Costa Rica. They are very well done anatomically speaking (well, they have nipples and areolas). They are pretty varied as well (is like they're a collection). Even so i don't think they belong to the Adrienne collection depicted in Shakey Pudding's gallery. Maybe the4 sexy mannequins' of crazyjose's post but i'm not 100% sure.
Anyway, nice pic. I got mine too but there was always a mall security employee that asked me to leave so they're pretty crappy. Anyway the second from the left looks rather well endowed for me


I had the intention to buy some but i had no idea how to pack them. For some resaon, I think that the big stores don't want them, they would rather cheap.
Anyway there are other threads dealing with them regrettably i only remember my posts:
gag photos thread the Djoser posts deal with them

still some pics are even worse

. People over those countries always make jokes about "Las maniquíes Tetonas"
