Real or Faux Desimone Plates?

Well, I'm trying to clear out the stash in the basement and I think that these plates are the real deal -- Italian Desimone 1964 -- but I'm seeking some reassurance before I try to sell them! Photos below. Thick potting and glaze, 10" diameter.

 

Heres the bottom of one of my pieces,that signature looks the same to me.

 

I know they say no two are alike, but this balloon man is so much clearer: https://www.worthpoint.com/worthopedia/de-simone-desimone-balloon-man-italy-1793925863

 

Your 'ballon man' kind of looks double struck.....but in comparison to @janetpjohn link's picture, they aren't IDENTICAL either............can't say anything else about it though.......

 

I have my doubts about these plates, and now remember that I had my doubts about them earlier. I noticed that the balloon seller was double struck and they aren't marked Italy. I will postpone listing them until I can rule them in or out. If Walter is around, maybe he can say yes or nay. I haven't seen enough of Desimone to know.
