This was an ad I recently received in the mail. It looks to me like this is an example of your brain knowing what it is supposed to say and tricking your eyes into seeing it that way. It might be better to have someone else look at it before it goes to press. If the three people mentioned in the ad all looked at it and didn’t see it, they need to slow down and really read it. Avoiding errors takes a little bit of extra time, but it is time well spent.
