MISTAKE MONDAY for August 19: Can YOU spot what’s wrong?

Can you spot what’s wrong in the image below? Please post your answer as a comment.

Thank you, John, for sharing this one with me. I confess that I couldn’t spot the error at first. Sigh. That’s why I try to keep improving my proofreading skills.

I post these challenges to raise awareness of the importance of proofreading.

NOTE: As of September, Mistake Monday will only be published once a month, on the last Monday of the month (for example, Monday, Sept. 30). I hope that you’ll continue to test your proofreading skills on Mistake Mondays.
