''Astoria'' pens produced in this period appear to be of the best quality, so they are very often treated the same way as [[Montblanc]], which erroneously (at least for models earlier than 1932) is considered a sub-brand. Having been active in the market for a few years, the ''Astoria'' are quite rare and therefore have a considerable value to collectors.
