I don't have a scanner.

The Avars exerted some suzerainty over the Slavs which varied, but they were eventually crushed because they had made enemies of more or less all their neighbours, Slavs, Franks, Greeks, Göktürks and Bulgars. They don't appear to have held sway for more than a few decades in their Northeastern territories.
As an approximation, I can offer this, a map of the time after Samo had shrunken the Avar kingdom.
