In order for me to properly assess what you have I will need to see images.
If you had already attached images to your initial posting, they are not showing for me here on my end.
Please send the photos at your convenience. There is not an extra charge to provide more pictures here.
There may be an +Add Files button or if there is a toolbar with a paperclip icon showing above the box where you type in responses, then follow the steps on this link for sharing photos:
There are two duplicate images attached here of the front of the dolls. Can you please check the back of neck/head and back of body for marks; they may be faint raise molded marks or impressioned marks.
Could you please send a photo or that, or try a pencil rubbing of the mark?
The material of the dolls is called 'composition', it is a molded sawdust and glue along with other materials like wood flour, resin and cornstarch that is then covered in a flesh tone painted shell.
The mark you see is not a maker mark, it is an aberration in the molding.
The style of the doll is loosely based on Shirley Temple and they date to late 1930's to early 1940's.
These could have likely been manufactured by Ideal.
On today's market, each doll can sell for $30 - $80.
Just checking in to see if you viewed your answer and if you are seeking further assistance?
Please let me know.
Great! Thank you for checking some more and getting back to me.
The 1940's Madame Alexander doll of Sonja Henie is the one that was issued with Sonja dressed for skiing. Here is a link for you of a visual example of all of the accessory pieces that came with this doll:
On today's market, this doll, if in mint condition and complete with all accessories, sells for a high average of $200 - $300 on today's market. In used condition with partial outfit, she sells for $60 - $80.
Let me know if I can be of further assistance to you on this.
