I have never seen these Little Friends 15" dolls that were made by Battat and released in 2001.
They would make perfect little sisters to 18" dolls.
When I purchased my Collector's Lane Mini Dolls, this booklet was included of the 1998 collection. Looks like Molly's school bag above.
If anyone has the 15" Little Friend dolls or CLK, please send in photos!
