Saw this photo on photobucket put up by a member called monstergram and don't know if this person is a member here or not or if these are the photos you remembered seeing. Fun posing though and this person should become a HF member if not already! Love them.
LOL. I assumed you were looking for the photo or thread but guess not. What kind of help are you looking for exactl? If these are posable or pose-n-stay skeletons all you probably need is rebar to help support them in the pose you set them in.
I believe I have 3 or 4 of the OT 36-inch Posable skellies now. Here's a link to the ones I own from them: http://www.orientaltrading.com/posable-skeleton-a2-25_1764.fltr?Ntt=skeleton I think they are great. Originally bought one and then have added to my collection over the years. The first year I bought them they were on sale for $20 something, but don't think I have seen them back on sale since then. Hard to tell if the ones used in the photo are taller but I'm guessing they are the 5-foot pose-n-stay ones.
