So here we have two early 20th century children, a boy and girl, the boy is actually doing something nice for kid sis. Anyone who has children, were children, know this is a by gone era. ;)

The boy is cute as can be in a pair of knickers and bare feet. His baby sister probably just wants the photo to be over so she can go for a ride.
After some research it appears that contraption she's in is called a Geneva Reversible child's push pull cart. What a cool item.

Nothing on the back to tell me who they might be. Divided card un-used. Slightly bumped corners and a sharp crease across the bottom pf the boys pants. Still a wonderful image.

Please see photos and email with any questions prior to purchase. Thanks for looking.
