[WM]: Help With a Watermark--PLEASE!!

["Richard Taylor" <vorticity4@gmail.com>]

The attached (.bmp)  image of the Mona Lisa has the same message hidden two times.
 

- One time using a simple black and white watermark logo.
- And one time using a carrier based on Smith ...; 32*32; -1/1

 

One of the two has a typographical error.  That is important as well. 

 

Can someone out there help me figure out what the messages are?  I don't have the first idea how to pull watermarks from images.

Thanks very much
