Well we left no stone unturned,
but still the mystery remains as far as I am concerned.
Are they kids or Political cartoons? and what is that machinery?

The letter form the Franklin Institute
Dear :
The Franklin Institute has, in its collection, the painting on which
the 3 cent stamp was based. On close inspection of the painting, the Chief
Curator noted that the objects to which you were referring were; an 18th
century electrical apparatus, most likely an electrostatic machine, and a
Leyden Jar for storing electrical charge.
I hope this begins to answer your question. Thank you for your
interest in the collections of The Franklin Institute.
Sincerely,
Susannah Carroll
Curatorial Associate
The Franklin Institute
