We originally thought this was an Upton Sinclair of California campaign pin. However, our good friend Jim Kirk, who knows his Sinclair items, informs us this is not Upton Sinclair, but a different Sinclair. We are not sure which Sinclair, but apparently it is not our friend from California. It is a 1-inch pin in excellent condition.
