Not sure on the date of the picture, but I came across it looking through the Effendi site: http://www.effendibikes.de/RaederBjoern/page/image33.html
Looks similar to a python set up, although a bit higher like an Air Bike? Interesting springs pulling the steering back to center, though.
I think it is the ChaCha-Bike (Charming Chair-Bike), originally designed by Wim van Wijnen. It is said to be the first center-steered recumbent.
