Tonner Tyler Wentworth Mosaic Modern Sydney TW 2405

My late brother was an avid doll collector (mostly vintage Barbie) but he also collected some other kinds. He has a large number of these Tonner Tyler Wentworth dolls. I'm just listing this to see if there is any interest in them. I know nothing about dolls and in particular this genre. I have to say they are quite impressive looking and the detail is amazing...
Please let me know if I can answer any questions but the pictures speak for themselves. She it truely MINT.
