In the '60s, Marx had a whole line of 6 inch figures that were sold individually in dime stores. There were cowboys, Indians, pioneers, cavalry, knights, vikings, WWII soldiers representing several countries, astronauts, superheroes and others. These U.N.C.L.E. guys from 1966 were part of a target game, and came with cardboard buildings. Don't know if they were ever sold individually or not. Far as I know, Illya and Napoleon (along with Mr. Waverly, below) were the only 6 inch character figures Marx ever made. As usual, they did a dang good job on the faces.
I possess only the five figures shown above, but there were several more. Most, but not all (including Mr. Waverly), are pictured below, courtesy of various eBay dealers.
