It appears to start with 'ex libris' which means that it came from the library of....someone. I can't read the rest, but my copy also had the same words and came from the library of a famous opera singer.
Yes the penned scribbles are identical to all the others.
She was not just the world's greatest opera singer in her time, but was multi-talented, she wrote plays, novels, short stories, librettos, and poetry; painted on canvas and porcelain; and translated and composed songs. She came from Prague and had an interestin history too, and collected Das Tri along the way. I have sold my copy to a member of the Royal Philhamonic orchestra who is a Bessler fan but also appreciates the link to opera.
