I was trolling through google images today trying to find a wide selection of grants and patents of arms to get some ideas for the scroll that I have to have done by this weekend (yeah, not even started yet, I know, bad scribe!), and while what I'm looking for for this project is English examples, I found some Spanish examples which were just way too cool:
First, Spanish Armorial Certificates has a number of pictures of 16th C (and later) Spanish grants of arms.
Second, there's Sixteenth Century Spanish Grants of Armorial Bearings to Indigenous Mexican Indians, with an amazing picture of one from 1559.
Third, this grant looks unlike any of the English ones I've ever seen, in its layout and format.
