Your own personal stamp 

Yep, you can do that.  You can feature your visage or a photo of your office or your favorite pet!  Costs a bit extra for these personalized stamps, of course.  Check www.usps.com for production details and costs. 

This is a terrific way to create a memorable impression for special message, low-volume mailings.  Could also be an effective “surprise” reward for agency staff members or a “thank you” tribute to your best referral sources.
