I had to start a Viking folder on my computer.
I don't know whose photo this is. I saw it on facebook and did some searching and learned a little about the topic, though not the photo credit.
These are thought to be 1,100-year-old gamepieces for the Viking game Hnefatafl. Maybe these are in the Swedish History Museum.
