You can find Marilyn Monroe Barbie doll clothing on www.ebay.com.
There's no such thing. The doll wasn't sold until 1959.
The Malaysia Barbie dolls have been on the market since 1986. You can find them at doll shows for about $1 each.
I believe the doll you are inquiring about is Free Moving Barbie from 1975. You can do a Google or an ebay search for the doll.
There is a website called newfreescreensavers.com where you can download free screensavers. Personally, I don't know what type of screensavers you like but there are a variety on this website so I suggest you check this site out.
First of all, you can buy the Barbie Video Girl, but you have to win the look-alike Barbie Doll.
According to Michael Augustyniak's book, "Collector's Encyclopedia of Barbie doll Exclusives," third edition, copyright 2005, she is worth $65.
There is no American Girl Barbie. Or are you asking about the 1965 bend leg Barbie, who is often referred to as American Girl? I don't know about her arms, but her legs are similar to the 1971 Malibu Barbie's, and some collectors have bleached the Malibu Barbie legs to put on the bend leg doll.
The best places are doll shows and the Internet.
You can find screensavers for free if you go online and search up under screensavers. Most of the screensavers are free with your desktop or laptop computer.
The only bride Barbie that I can find for 1996 is the Toys R Us My Size Bride Barbie with red hair. Is this the doll you have?
