This must be the one since it was the last card I needed to complete the set that I began years and years before. The card may be one-of-a-kind. A kind gesture from a very advanced collector who occasionally contributes to this board enabled me to acquire this card and complete my set. He said it was the first card he had sold out of his collection since 1985. There are rumors of another example in a very old collection, but the collector was unable to find the card and I am suspicious that his memory regarding another example of this card is fuzzy after a few decades.
