Marino Marini Need Help, OLD Estate Attic Find, UNKNOWN IF a Print or Original??

I did find out the name of this is "HORSE & JUGGLERS" The Style is MIXED MEDIA, believe to be the style GOUACHE, Watercolor border. The other Horse and Jugglers I seen Border is different. I believe I posted it years ago with no response. Marino Marini did these horses. I am trying to find out if this is an original, or, if a print. This came from an Estate attic sale about 8 years ago. the paper is heavy and shows foxing. Look at the way it's painted. any help would be greatly Appreciated Also measures 20 x 26 inches. is it signed in the block as they call it or is it his actual signature with a the brush???????
