Help About This 1920 German Book "The Little Stamp Collector"

Have had this book written in German (I assume) that translates into "the little stamp collector". Written in 1920 I'm assuming by Danner. It is in rough shape and the pages are fragile with at least one with damage. I have nearly thrown it in the trash many times but have always slipped it back into its storage bin and forgotten. Multiple searches have provided nothing. Do any of you think there is any interest to collectors or historical value in keeping it??

In the pocket nr. 61. Westentasche is a cardigan / vest pocket. This is nr. 61 in a series of pocket books.
Verlag is the publisher, The inscription means it was published by G. Danner from Muehlhausen in Thuringia.

The little stamp collector in the vest pocket, probably, should be read as "The little stamp collector" in the series of pocket books.

Here are more editions from this series: https://www.booklooker.de/B%C3%BCch...lag+G+Danner

Thank you.
So other than the mention of stamps in the title this is just a story book and has no real postal value?? Do you know if the title is correct that it is about a boy that collects stamps? Don't spend time looking as it's not an important fact.
