This Estey Organ Company advertising card dates from around 1882 to 1900.
This card tells several stories at once, which led me to believe that these are not just randomly painted people, but that they could possibly even represent members of the Estey family.
The room itself is also full of clues related to the Estey family, and the Estey Organ Factory in Brattleboro can be seen in the background through the open patio door.
I tried to find Estey family members who could match the people on the card in appearance and age.
Furthermore, I searched for a possible house in Brattleboro, VT, USA, that is connected to the Estey family and could correspond to this room.
There is no official information that links this card to Estey family members or that provides a location for this room.
The assignments of the Estey Family members and the selection of possible locations are my idea and are based on my research on the Jacob Estey History series.
