The image caption says it's jugglers/artists travelling. It's a coloured xylograph, single-leaf prints from about 1450. Today at the Herzog-Anton-Ulrich-Museum, Braunschweig.
What I really like about this picture is that it shows a lot of medieval household items. You can see half a kitchen sticking out from the woman's carrycloth around her back... and as a true multitasking female, she's not only travelling, keeping all the household stuff, looking after the livestock (see the chickens on her head?) and looking after the baby, she's also spinning at the same time. Amazing. And modern folks say there's a lot of pressure on women nowadays...
