I have a quick question...I have a very large MTM collection of about 300+ pieces. It ranges from pencils to mugs to signed plates and cells...
I have rare candles, one of a kind items, a life size MTM authentic costume (not the ones on Ebay but the one from a theme park).
I am looking to sell if, but don't want to do it piece door piece on Ebay. I started collecting in 1979 and still have things that I can find up
until last year. However I am forced to sell it all off as much as it kills me.
Do u know anyone who may be interested, of know a site where REAL Marvin fans are and not the Ebay "let me get it because its cute"
kind of buyers are.
I would break it up if need be but its taken me such a long time to collect that I really wouldn't want to.
Please...and info u can pass along would be meer then helpful!!
Thanks ahead of time =)
