HI, I have 2 very old Currier & Ives framed pictures 1 is The Four Seasons of Life: Youth "The Season of Love" in the bottom left corner it says J.M. Ives. Del. Drawn by Parsons & Atwater. The 2nd is The Seasons of Life: Old Age "The Season of rest" both marked with the same in bottom left corner I'm wondering if they are originals or not?
