3 Early Dennison Halloween 1920S Place Cards Cat Witch Jack O'Lantern unused

I don't believe that any of these three place cards comprising this lot were actually made by Dennison. I think they were made by another company with or without permission from the original designing company. The cat face has a strong resemblance to one of Dennison's designs, but their name is spelled out in the artwork along the inside of one ear. This cat face has rather blurred art there, leading me to believe this was not made by Dennison. The JOL is from Hallmark or another firm with the witch being by another manufacturer altogether. Given the similarity of the edge colors and the uniformity of the "Made in USA" printing on the reverse, I feel quite confident asserting that these were made by an unknown third party with or without authorization. I feel these are therefore around $15-18 each, so the buyer paid a premium, almost certainly in the mistaken belief they were buying a trio of Dennison items. 

06/21 Update: The buyer of this set contacted me to say he would be contacting the seller. Here is what I wrote to him on Monday: "The seller of the place cards is a good person who is really quite knowledgeable about vintage Halloween paper. I understand how the mistake was made given that the cat face is an iconic Dennison image, and all of them had the same look and feel. The trio of items is still great – just not Dennison – and not commanding the premium that Dennison so often brings.'
