Tour the World Bottle Cap collection. Complete & Signed

My parents owned a small general store in Terre Hill, in Lancaster County Pa. In 1962, Coke had a promotion of 100 different bottle caps all numbered showing famous landmarks from around the world; Statue of Liberty #1 through Old Sugar Mill - Virgin Islands #100. At 11 years old, I took my bike every Saturday for two months and went to the two other locations in town that had coke machines. Being a small rural town, the business owners would open the machines and give me the caps. Once I had collected all 100, I mounted them on poster board with the back page from a Boys Life magazine somewhat in the center. (The page displayed the caps). My Dad boxed the collection up, and sent it to Coke's General Office in Richmond, Va. Several weeks later, my collection was sent back signed by the Chairman of the Board and the President of Coke, with an acknowledgement letter pledging a free case of coke to be delivered by the Lancaster Bottling plant. (As a side note, I did get the case of Coke, which being a kid, I did drink. . .but being a collector, I did keep the case and bottles). My Father framed the collection with the acknowledgement letter displayed. Through the years, the glass got cracked, but that just ads to it. It still hangs displayed on my Den wall. I would imagine there are other complete collection, but I would guess very few if any others signed.
