This was a tough one to scan and clean up.  It’s 19.75″ by 9.75″ and, over the years, it’s gone from white to a light ecru, but not a consistent shade.  Three people are on the phone in their photographs.  I don’t know what to say to that.
I didn’t actually participate in this one.  In a later year, I actually got tossed off the telethon because I was singing so badly and loudly.  Never did fit in, never will.
