Joseph Hoffman Stendig was definitely the importer. DO further research as his furniture is pricy and collectable especially mid century modern examples shown in your pictures Nice find. I hope you stole them!
All I found so far is that he imported furniture from Finland between 1954-1976.
I'm thinking at least several hundred apiece.
That's based on Swedish designed wood chair.
And I actually think I'm low balling.
You did real good!

May I ask what you paid for them?
