You guys know about old Bovril advertisements? There's kind of a lot of them. This is one of the more infamous ones. I don't know if the pope actually had anything to do with this ad, or if they just used his image unauthorised; The History of Bovril Advertising, which I attempted to scan this ad out of, just dryly notes that the claim here is possibly one of the greatest ever made in advertising (paraphrase, I don't have the book on me right now).
wait what is bovril
Bovril is a sort of beef extract paste that (I believe) is popular in the United Kingdom and has been around for a long, long time. You'd put it in hot water to make "beef tea", or spread it on sandwiches, or also maybe put it in milk to make... beef... milk?? You can buy it in Australia but it's vegetarian, made with yeast extract (like vegemite) instead of beef. I think this is due to export/import restrictions? I've tried it, it just tastes like vegemite, but I assume beef bovril tastes more like beef.
Also, it's kind of hard to scan a spiral-bound book with a normal household scanner that doesn't like it when you open the lid, so this scan, the only attempt that worked, is blurry up the top and has jpeg compression. I don't think it's high-quality enough to replace the low-res image of this ad on Wikipedia, but it does show that it's shaded with hatching. So I guess that's interesting. Of course there are higher-quality versions of this image that appear to be photos or scans of a poster that is now extremely expensive. And somebody is selling just the image on Etsy for AU$4.39. It looks like a really good image - where did they get it? What are Wikipedia's rules for uploading reproductions of public-domain work of questionable provenance, I wonder...
