Todd has collected mementos from his mother Debbie Reynolds and sister Carrie and says the display will include items that "people don't necessarily associate" with the late actresses, reported People magazine.
"There are a lot of things that we have of Carrie's that we're going to put on display in the new museum with Debbie and Carrie. So we are going to rebuild Carrie's writing room, and we're actually going to put out her writings, long hand. Carrie did not use a computer. So we're going to show people the process that she used to create.
The collection also includes the "Star Wars" icon's writings from the initial days of her playing Princess Leia.
"There's a path to Princess Leia. It didn't just jump from zero to that. So that path is interesting. Princess Leia actually wrote long before the Force was with her. There are amazing early writings of Carrie's that are very interesting," he adds.
While his sister never wrote biographically, Todd says his collection includes short stories by the actress-author.
