This vintage cabinet card in folio of two sisters is probably circa 1920s. I am estimating this based on their clothing, hairstyles, and accessories with which they've adorned their hair.
The photography studio, The Main Photo Studio, existed in Boonton, New Jersey at 316 Main Street, and one can find a photo online of the building in its current incarnation today.
The folio housing the cabinet card measures 8.5" x 5.5".
Please note the areas of wear on the folio as shown in the photos and the black mark in the upper right hand corner of the folio as seen in the last photo.
Thank you for looking.
