Besides what Vintagebrett said...
Back in those days the sporting goods business and player endorsements were not always on a national scale. There were many small companies that marketed their products on a regional basis and it wasn't uncommon for them to sign endorsement deals with popular minor league players from their area.
Baseball itself was not as national in those days, with all of the Major League teams being concentrated in the eastern half of the US. For much of the rest of the country, the minor leagues filled the void and were a thriving enterprise.
Also of note, as you research this glove: While the Hunt auction refers to this endorsement as "Hickies" (with an "i"), the one reference book entry I found, and the post to the other web site I linked above, spell the name "Hickles" (with an "L").
A google seach of this name under either spelling turns up exactly one listing for each!
