0823B223282 Lot of Three RPPC Postcards: I believe these are the same two boys and horses in these three photos.  In one photo the older boy is harnessing the horses to the wagon; one has them sitting in the wagon on a load of cornstalks; and one is from the back of them riding in a field in the wagon (open-back wagon).  

One card is posted 1909, but the other two are unposted.
