Genuine Canon PowerShot S3 IS 6.0MP Digital Camera. 

I am the original owner of this Camera.  It is in very good condition.  All features of the camera work and it operates as designed.  It comes with the original manual and shoulder strap.  Memory card and batteries are not included.  It has some superficial wear marks noted on the bottom of the camera, and where the lens cap connects (See photos).
