I made logo with "smilling face" concept #34 and #35.
Visually, you'll see a smiling face. But the deeper meaning when seen, you'll see a couple of friends who are playing fun. On the right side when examined will be seen "Helping Hand" to keep them. "H" and "I" in the word "Michigan" has the meaning of books arranged neatly.
Does this concept works well for you? Let me know if you'd like to see any other changes.
