Photograph of the Frank S. Schreck family posing for a portrait. From left to right: Frank is standing behind a drum and dressed in a tasseled military uniform, complete with a saber at his side; baby Ursula is sitting on a tall stool and wearing a white dress; mother Ursula is in a dark dress, sitting down and holding a bow; child Enrique (Henry) is seated and wearing a uniform like his brother's; Frank S. Schreck is seated next to his wife, wearing a dark suit, and has his left hand on son Alfonso's shoulder; Alfonso is also wearing a military uniform and holding a bugle; Leo is similarly dressed and has a bow across his back. There is a painted woodland scene in the background, and the family is standing on an animal skin rug. The reverse side of the photo contains two handwritten notes; the first says: "Matamoros, June 3d, 1899 To our dear sister Mrs. Anna B. Schreck and her dear and sweet family, as a token of sin-cere affecton. Frank Schreck and Ursula Fuente[...]r Schreck." The note in the lower-left conrer says "Oct. 5-, 1956. To my cousin E. E. Schreck, Leo. M. Schreck."
