Chris: Your Mann card is one of many produced by Globe Printing Co in San Jose, CA. They produced several minor league sets. Look under Globe Printing in the SCD and it will show a list of sets they produced. Many are very hard to find such as Jamestownm Miami Beach, Ft. Worth etc while Soo City seem to be available from time to time. Apparently their shop flooded and destroyed a lot of their products thus a factor in their scarcity I assume.
