Excerpt:
A month after an anti-Muslim billboard disparaging the Prophet Muhammad went up along I-465 and gained national attention, a Chicago-based Muslim group is firing back with a billboard of its own.
Dubbed the "Truthful Man" by the minds behind it, the billboard is a direct response to the "Perfect Man" title given to the other billboard. The two billboards are across I-465 from each other on the east side.
The new billboard reads: "The truth about Muhammad. Get a free book on his life. Call 800-662-ISLAM." Anyone who calls the number can ask any question about Muhammad or Islam and request a free biography about Muhammad.
