Zeenuts are a fascinating and fun series to collect, but you learn along the way to expect numerous anomalies. There are several typesetting errors, players names are misspelled or completely misidentified, and team attribution errors. Very few of the errors were corrected, at least in the same year (Eddie Matteson / Matterson in 1920 is an example of a correction). This is a series that you can spend a long time, in my case going on 42 years, and still not fully understand the complexities of the set. Is it possible that the Horstman error was corrected...Absolutely. It just has not been discovered by modern collectors...yet
