My parents are just back from their vacation in Houston. My dad just sent me this marvelous jpeg along with the note below:

Dear Kathryn and Karen,

   Attached is a .jpeg file made from a half-page advertisement in the 1877 Houston City Directory advertising the Solo Saloon, a drinking establishment owen by my great-grandfather (and your great-great-grandfather) Charles Kinzbach.

   We found this last week in the archives of the Clayton Library in Houston.

Love,
Dad
