A Basel German Rhyming Dictionary in a bookstore window

This morning, I walked past a bookstore with a Basel German rhyming dictionary in the window. For this text, I looked for an estimate of how many people speak the language, but I couldn't find one, so I'll just say that for Basel-Stadt, the number must be less than 200,000. It's somewhat surprising that a publisher would put out a rhyming dictionary for such a small population. Yet the percentage of people writing rhymes in Basel is relatively high: participants in Fasnacht, Basel's carnival, write many verses every year, both long rhyming poems handed out during the day at the parades and short rhymed verses sung as "Schnitzelbangg" in the evenings.
