Wanted to add an addendum to the above. Since you have posted in the "What's it Worth" section, I'm assuming you are interested in value. I personally can't place an exact value on anything here, but will say that it's all very collectable. The flag, the Buisiness college broadside, and the bait box all date from the late 19th to the early 20th centuries. As I mentioned earlier, the German page appears to be 18th century paper. If you look at it held to a window, you might see "crosshatching" which are artifacts from the paper making process left from that era. However, that being said, you can buy "laid paper" from any art supply store today. The 45 starred flag was only in existence for very few years so are highly prized by collectors. The flags, bait box, and pharmecuetical bottles are most likely the most sought after of your collectibles and should sell well at auction. As with any auction item, the more detailed your research is the better the item will sell.
I have not contacted them since the creation of the web, but the National Bottle Museum has helped me in the past find the history and value of antique bottles before. They are very nice and helpful people if you contact them. I do know that they have an annual auction you can consign to.
Good luck with the items, and I would have a great deal of regret letting go of any of it.
