Mein Gott that was fast! Thanks. The kelly pool pic is a good thing. Picture worth a thousand words there. A couple of side topics: 
What do you think about the recent (today) addition to the glossary of "killer pool"? Seems to me we don't describe games in a glossary (not sure if the game is even notable enough for an article).
Since you may be more familiar than me with licensing at commons, do you think I can properly upload an ebay auction picture showing the cover of the 1923-24 Brunswick pool table catalogue; what would be the licensing, PD-old? (if you aren't familiar with such issues, don't bother, just thought you might know off the top of your head).
I like all the recent changes to balkline except for the last. The old image and description gives the article an air of "we are dealing with a long history of historic importance." It also serves as a more general (and very interesting image) until people can follow along with the more detailed images and their descriptions later in the article. Also, the image you took from later in the article was tailored to the section it appears in and with a description that will be meaningless until readers have reached that point in the text, not to mention that the article was balanced with images and now has a hole at the end.
