This is a two-color patch with a gray background and black lettering.  At the top of the patch, is sewn "25th."  At the bottom of the patch is sewn "LONDON, OHIO."  In the center of the patch is an outline of a CD 260.  On the skirt of the insulator is sewn a five-pointed star.  On the down of the insulator, in an arc, is sewn "MID-OHIO" followed by, in a straight line, "INSULATOR/ SHOW."  The patch is approximately 3 inches wide and 4 inches tall.

These were given out Sunday afternoon at the show to dealers for free.  The CD 260 is a favorite of show host Steve Blair and is used in ads for the show so was a natural choice for inclusion on the patch.  About 100 of these patches were made.
