Does anyone know what the value of the 1968 Major League Baseball Promotion Easel cards might be?? These appear to be very scarce. For those that don't know(and I was one of those prior to trying to research these). The cards were meant to be glued on the back of the plastic mini-plaques so they could stand up.

There are none of these on ebay, except for the two with the plaque lot. None I can find on Google or Worthpoint....
