ICF New York 'floating' sofa made in holland  

I have two, matching vintage, ICF for New York 145 E. 57th Street New York N Y (ICF first location?) 'floating' sofas made in Holland.  Burnt orange.  To the best of my knowledge, this could be purchased in a three-seat sofa,  loveseat, chair and ottoman. The skirt could be recessed and painted black or moved forward and upholstered.  Including pic of the sofa. I also have a pic of the chair and the tag that came on each but I can only upload one photo.

Can anyone tell me when they were manufactured,  production number and who was the designer?

Sincerely, 

Perplexed
