Letter from Moses Soyer to his grandson, Daniel, including sketches of dogs, five different breeds. Handwritten watercolor text instructs Daniel to identify which of the five dogs is "Martha", and to circle that one with a red pencil. The dog in the lower right has been circled in red. Date is based on a guess at Daniel's approximate age when this would have been written (Daniel was born either 1958 or 1959).
