But we’re not so used to looking at blackletter, and so a manuscript facsimile of that type isn’t quite as tell-tale. This is particularly true when the facsimile doesn’t have the print nearby as a point of comparison, but the difference isn’t necessarily glaring even looking across the gutter to the early printed page:
