This image is taken a bit out of context. It is mocking the supposedly Napoleonic ambitions of a Moravian nationalist and Catholic literary figure named Karel Dostál-Lustinov, who was the driving figure behind a fraternal gymnastics movement known as the Eagles (think of parallels with the YMCA). What is striking for present purposes is that the Eagles are being called to prepare for battle (against the Republic?), and they are doing so with disinfection spritzers. (In Czech the verb seems to hint at an adjacent meaning of “cleansing.”)
