From The Pioneer Record, Ida Grove, IA - April 12, 1906.
-----------------------------
Mr. C. Muma, the veteran photographer, who has been in business in Ida Grove the past five years and for many years before that was located at Holstein, Iowa, has sold out his gallery here to Henry Rothenberger and will retire from active business life.
Mr. Muma will remain with Mr. Rothenberger the remainder of this month for the purpose of finishing up his own work and starting the new proprietor out right, and he will than travel four or five months for health and pleasure. Mr. Muma's eyes have been severely strained in his work as a photographer, and he intends now to take the rest his long labor has earned for him.
Henry Rothenberger hails from Switzerland and has only been in this country a short time.
