There's no doubt if you enjoy German 20th century graphic and visual arts, the Notgeld bills will provide some of the finest, striking colorful examples - Notgeld or "emergency-money," (pronounced note-gelt) was issued through national, state, local and private channels to financially assist Germans during the lean years after the First World War.
Often these bills portray a wide range of images from the pages of German history - legends, events, geography, family names, companies, large regional and small district advertising, children's tales, religion, industry, etc, etc... Many various styles, themes and artistic concepts can also be seen that reflect the "Völkish-movement," that came to be so heralded and cherished by the "browns" of the NS regime.
Much larger than stamps, (for us old dogs with faltering peepers to enjoy) collecting these brilliant gems is still very affordable, at times they're downright bargains! Even common tinnies in good shape are expensive when compared to these vibrant historic illustrations.
There's much to be enjoyed in this area of collecting with lots of pertinent information out there on the web to help those with an interest. Lots of good articles have been written on the subject in militaria-related periodicals as of late, too.
