I'm sure I've seen the back drop from the proms in the sims 3 on an image for the sims 2 somewhere but I can't find it at all. I can't even find the original image now, I sear it was on the homecoming pose box page by lovelacing but its not... I've attached a picture from sims 3, if the object doesn't exists but is just a jpeg backdrop done in edit that may explain it maybe?

I have a version here (login required), picture of the backdrop here. I think all the TS3 (EP, not SP) backdrops are included in that upload.

I think I've seen that one elsewhere, too, but can't remember where. I know the seasonal ones can be found here at MTS, but the others are a bit all over the place.

thank you !
