Lot of 4 Dave Stevens Comic Art Postcards 1980s

Up for a Buy it Now is a lot of four comic art postcards featuring art by Dave Stevens.  These were all loose in a box; stacked nicely, sorted by like kinds, but no obvious 'set' that they went to.  Not sure who manufactured these in the 1980s. Postcards measure 4" x 6." Very good condition; all have a slight curve to them due to the way they were stored in the box but no nicks or dings.  This lot will not come with a COA.  Free US shipping.
