I did Jarl Asbjorn back in the '80's. I was active in the local figure society, the Minnesota Miniature Figure Society, and did quite a few collector figures at the time.
I believe the figure is a Post Militaire Series 66 viking. I did the shore and rock carving with balsa and Durham Rock-Hard putty, and the water is a two-part resin product. I can't remember much more about making the water -- looking at it now I believe the waves are clear sealer, like you would use on a sink.
Anyway, without further ado . . .
It was fun photographing the Jarl, and I am sure I will share other of my past collector figure pieces from time to time.
