It's from Chicago Pennant Co and judging by the tags I think its 50's-60's. I have seen others that are easier to date (use the word "university" instead of "college" with the same tag) and those are generally in the late 50's or 60's. I think I am going to leave this one alone.
I do have some others. I am very interested in these types of pennants. I created pinterest page that I continue to update. It has most of the one's I have seen. Some are hard to get good pictures of so they havent made it. Check it out:
