You are looking at 2 identified photographs from the Walter family of Lancaster Co., Pa. There is one 4x6 photograph identified on the back as "LIZZIE WALTER" taken READING, PA. and the second photograph measures about 5x7 and it is of LIZZIE'S two daughters IRENE & FLORENCE WALTER. Both photos are in nice shape with appropriate wear and tear and a few dirty spots (see scans).
I have done some research on these photos and this is what I've come up with:
Photograph 1 - ELIZABETH "LIZZIE" MUSSELMAN WALTER was born May of 1875, I obtained LIZZIE'S maiden name through 1910 BRECKNOCK, LANCASTER, PA. census records, her brother ABRAM MUSSELMAN, born 1866 PA. was living with her and her family. According to 1900 BRECKNOCK, LANCASTER, PA., census records, ELIZABETH'S parents were JACOB MUSSELMAN born January 1837, PA. & ELIZABETH born February 1839 PA. LIZZIE had the following siblings: ABRAHAM "ABRAM" MUSSELMAN born June 1866 PA. (I don't think he ever married), Mary A., Mathias, Wilson & Frances.
1860 Brecknock, Lancaster, Pa. census
Jacob & Elizabeth Musselman - no children
1870 Brecknock, Lancaster, Pa. census
Jacob, Elizabeth, Mary A., Mathias, Abraham & Wilson
1880 E. Cocalico, Lancaster, Pa. census
Jacob, Elisabeth, Mathias (listed as Masias), Abraham, Wilson, Frances & Elisabeth (pictured)

By 1910 Lizzie is married to Charles Walter and living in Brecknock, Lancaster, Pa.
Charles J. Walter was born abt. 1872 Pa.
ELIZABETH "LIZZIE" MUSSELMAN and CHARLES J. WALTER, married circa 1906.
Photograph 2 - As far as I can tell, IRENE & FLORENCE WALTER were the only 2 children born to LIZZIE MUSSELMAN & CHARLES J. WALTER. IRENE was born abt. 1907, FLORENCE was born abt. 1909 .
1910 FAMILY IS LIVING IN BRECKNOCK, PA.
1920 FAMILY IS LIVING IN BRECKNOCK, PA.
1930 CHARLES, ELIZABETH & FLORENCE M. are living in BRECKNOCK, PA., Irene is absent so it's presumed that she is now married.
