Vintage Metal Advertising Corn Cob Holders (?), Cleveland,O.

I think these are advertising corn cob holders (?), the advertising on the reverse side is:  "SCHWALB'S DELICACIES, 1005 Huron Road, Cleveland, O."  They measure 3 1/2" x 3/4" at the widest part.  They picture an ear of corn on the front side.  I do not know what the hole at the top is for unless it was to hang them.  As you can see from the photos, they do have some spotting, I have not attempted to do anything about cleaning them.  I am selling them "as found".   Free shipping first class mail with delivery confirmation.  Insurance is at your option.
