1906 Ticket Help

[prewarsports]

So I found this ticket recently in a 1906 scrapbook. I know for 100% certainty this dates to 1906, the high school senior whose book it was found in noted he was given the blank book for Christmas in 1905 and nothing was in there past Christmas 1906 save a few random things jammed into the back.

When I first saw the ticket I simply thought it was a cool 1906 White Sox ticket from their championship season. However, it gets better because the game number 1 on the stub indicates this was either from the World Series (first game) or opening day. I believe it is the World Series for a few reasons, the only other 1906 stub I have seen had a 50 cent price whereas the only known White Sox World Series stub had a similar $1.50 price.

I am at a dead end and as far as I can tell, there is no other game one ticket known (at least none I could find) so perhaps someone on this board that knows tickets could help me determine absolutely if I have an opening day stub or a world series stub.

Thanks in advance
