I haven't heard that story before. Do you know if Gary told it here - or is it posted on Greg's board?

"I am afraid to say anything more about it in open forum but I vividly remember drawing it."
"it was the woman's head slightly tilted and even with the hair pulled up and also the rocky top of the bottle"
"Thanks for taking the time to reply with such a lengthy letter and thank you for believing. I am glad that someone does....I did not really want to be in the spotlight but all my life, well since the time the 5th series came out, this was always something special to me. My sister even remembers when I drew it."
"The Topp's company never sent the batch of drawings back to me that had the drawing for Head & Boulders, but when I sent some later ideas in, they sent those back and said they had their own staff of people creating the designs"
Great job on this Gary, where ever you are. You will be remembered forever by some that know you created this cool sticker!
