Wald- und Feldbrevier. Jugendlieder by Rudolf Hans Bartsch

In English the title translates to: "Forest and field breviary. songs of Youth"....i think. Can anyone help me translate or tell me about this German book I found today for one dollar. Flipping through it....it is in decent condition. Looks like it was released in 1921, and maybe it is a book of poetry? I found this on wiki about the author:

"Bartsch wrote novels and short stories, which, according to today's critics often glorify the old nostalgic Austria. Gero von Wilpert ( for a very fertile, non-critical narrator of the old Austria - kind with sentimental novels and short stories, cute and bittersweet love stories of playful levity) ...[1] His novel about Franz Schubert, Schwammerl (mushrooms), one of the most successful Austrian books before World War II, served in 1916 as a template to the operetta Das Dreimäderlhaus by the composer Heinrich Berté, which was also filmed several times."

I am not sure but there is a picture of a man, but I don't think it is the author. It looks like....looks like that person signed it in pencil below. I hope that person is famous. Maybe someone was trying to copy the signature above though.

Thanks!
