From the Hans Christian Andersen biography "The Life of Hans Christian Andersen. Day By Day", written by DPhil Johan de Mylius:
In this year and completed in 1875
Release (in Prague) of a collected edition of HCA's fairy-tales and stories, written in the Czech language.
Februar - March
Presumably around this time, Nicolai Bøgh receives letters received or written by HCA - which have been kept by HCA - for perusal, with later publication in mind.
