Two vintage cardboard Halloween black cat faces. No maker or markings on either cat. It may be a possibility the one face is somewhat older than the other. They differ slightly in the weight of the cardboard and the deeper coloration of the face. As you notice from the photo, a difference in coloration of the cardboard backs, too. The one may be from the 1940s - 1950's, where as the other might date 1950's - 1960's. Anyway this double trouble pair are looking for a new home.
The one with the brighter coloration is in very nice condition. As you note, the other face is missing a slight tip of the chin. Also there is some damage around the string hole at the top. I believe this one may be the older one.
Size of both are the same, 4-1/2" wide at the widest point. 5-3/4" long from the tip of ear to the point of chin.
