Hi Elizabeth,

Thank you for contacting Mearto with your appraisal inquiry.
There were several companies that manufactured this style of chair from the 1920s/30s onward; most were marked so if your chair has a mark (often under the seat), please let me know and I'll update this appraisal, which I've assumed has no marks.
Based on the photos and information provided, and subject to examination, this is:
