A multi-panel cartoon by Karel Stroff from Humoristické listy (Prague, 1915), drawn at a time during World War I when cities were beginning to experience food shortages, and producers were frequently suspected of overcharging for ersatz materials unsuited for human consumption.
- The famous Professor Mikrobec pondered: So many diseases can be averted by vaccination, and one of the most terrible is raging in today’s war. I have to find a serum against it.

2. At the “qualified authorities”: Rest assured, gentlemen, that my invention will not disappoint. We can start tomorrow.

3. It’s nothing, sir, vaccination is healthy. There are so many diseases today…

4. For Christ’s sake, old man, what are you doing? Throw away all the crumbs in the morning, and now make buns like there’s no tomorrow… Are you crazy?
I’m not crazy, but that’s the way it is, that’s the right and honest thing…

5. People cheered on this miracle–

6. (Signs reading “Glory to the most useful scientist!!” and “Long live the inventor of the serum against extortion!!”)
and the grateful nation demanded enthusiastic applause for the professor.
