Hope this helps Leon, here's an article on the 1906-07 season in Weiser. Sounds as though the fans in Weiser did not really warm-up to the young man until his phenomenal 1907 season (last game for them July 21, 1907). No references to "Weiser Wonder". I agree it would not make sense to promote a young man who had just left your town. Sounds as though they tried to bribe him to stay, offering him a cigar store downtown.
