Were book shops of Europe's past really full of books? Well, here is an #earlymodern bookseller from #Dresden, Germany, in front of his boxes. Yes, boxes, not books.
In these boxes unfolded printed sheets (of a certain publication) were stored. This is what you would have seen, next to small amounts of bound books and small publications, in a typical early modern book shop. So #bookhistory is sometimes a history of boxes too.
