This image is from the Chronica Hungarorum. János Thuróczi wrote the chronicle - a history of Hungary - which was printed in 1488 in Brünn. It was also printed in Augsburg. (This link provides background information on early printing in Hungary.)
The image depicted here is from the Augsburg edition which includes “hand-colored woodcuts of Hungarian kings and battle scenes.” The book also contains gold work, as described by the web site of Hungary’s national library:
The publisher of the Augsburg edition dedicated the work to Matthias and used gold paint for the dedication of this luxury copy printed on parchment. Today this is the first known book printed with gold paint.
This colored woodcut is of Attila the Hun.
