History of Work Information System

I stumbled across this website while looking for pictures of 16th-century milkmaids. It's an encyclopedia of the history of work, and seems to be exclusively European. I haven't run into anything that isn't from Western Europe, yet -- that is, nothing from Russia or Eastern Europe.

There are engravings from the 16th and 17th centuries there, of various professions. For example, this plate by Jost Amman of a cook at work (16th century Germany). I will note that the cook is really, ridiculously burly. Look at his left arm. What the hell, Herr Amman?

Oh, Jost Amman, you strange man.

Can anyone explain to me what's going on in this picture? It appears that the woman sitting in front of the bathhouse proprietor (the dude standing up while wearing bikini briefs) has large knobs stuck on her shoulders. I'd read the text that is supposedly about the picture, but it appears to be about an apple seller, and . . . there are no apples!

And the blacksmith is less burly than the cook. What kind of place was Germany in the 16th century?
