There's been a couple on ebay. One listed at $2500 been on and off for awhile. The other one starting at $1 ends in a few hours but you have to pick it up so just depends. On something like this value is always what someone is willing to pay for it. It's so big some people may just want it gone.
I was recently doing some googling regarding the lifesize Simpsons prop and cant believe my luck in finding this website & discussion - which I know is old but I'm hoping someone will reply.
I am from Australia and have what I believe to be one of 3 lifesize family props that came in to Australia when the movie was released. From what I have been told, a set went to 3 Queensland cinemas however one got smashed (not sure how), the second set is unknown whereabouts and I have the 3rd set (including couch & other props) which I bought from a lady last year and incorporated it in to my 2013 Christmas display (see link - Santa Raedel at Craigslea Drive, Caboolture - 4510TV - Caboolture )
I was hoping to find out more information as I came across someone recently selling Lisa in Australia and I decided to buy her as a spare as this might have come from the 3rd set.
I also saw someone selling another Lisa on the USA ebay site and that person said there were 10,000 of these made but I was told from someone else only 1,000 were made.
I know this is an old thread but I was hoping to find out more information as the set was a real hit in my display – and especially from SenseiMonkeyBoy who says he designed them.
