Sixth-Plate Daguerreotype of Smiling Mother and Child by Higgins, 1850s
The mat of the image on the right is stamped “Higgins”. There were several daguerreotypists with this name in Philadelphia in 1850s-1860s, but this is probably Benjamin L. Higgins since Craig’s Daguerreian Registry notes that he is know to have stamped mats “Higgins”.
