Information on Leonardo Collection Doll?

There are lots of available Leonardo Collection dolls listed for sale online but finding this particular doll will be almost as difficult as finding the proverbial 'needle in a haystack'.
In my case it would have to be a visual search and that means checking every site that has dolls - either for sale or just pictures
and if you check Google alone there will be plenty of dolls to check.
Even if you had a name it probably would not help very much as most sellers will not have a name as names were only shown on original tags or the very cheap boxes that were usually damaged easily and thus thrown away.

I hope that another member, PGHgirl, will be able to help when she checks in.

I can only suggest that you join some of the doll forums and ask your question. The problem with this is they usually want the doll undressed completely with pictures of full front and full back both clothed and unclothed. Also a picture of markings on the back neck and a full face picture. They really need these for older dolls but for best results pictures are necessary.
They will also want her size (inches).
There are several Facebook groups.

Online right now there are thousands of dolls listed and searching for one doll out of all of them is almost impossible. I did narrow down the search and tried to look at all the Leonardo dolls that were being sold. This company mass-produced dolls so it has hundreds of them that they made and people are trying to sell right now. What I would do is take some good photos of the doll's face and try and do a reverse image search to see if you can find this doll.

A lot of times Google will have different doll images that you can look through. In some cases, a person might have posted this doll online or taken a picture of the doll. You might get lucky to find out more information about the doll and maybe the name the company gave her. If you can do this then it will be easier for you to search for this doll by the company who made it and the name of the doll to see if anyone is selling this doll online.
