RARE Vintage Halloween nut cup party decoration

This is a very intriguing item. I have never seen it, or anything similar, before. I am curious as to the purpose of the holes punched in the base. What was this item designed to hold that such venting holes would be required? (If a reader has a theory - like Ross Perot - I’m all ears.) The imagery is super. I especially like the rare graveyard scene. (Graveyard scenes are surprisingly uncommon in the overall iconography of vintage Halloween.) I got a kick out of the directness of the seller when stating, “This is not a grand showpiece, but an interesting piece nonetheless considering it’s a rarity.” AMEN to that! I would love to have this as part of the collection, but the condition is too rough for me.
