Olle Eksell and Egon Moller-Nielsen on the Playground, Stockholm, Sweden

I've featured Egon Möller-Nielsen's trippy playground constructions on the blog before so my spine tingled when I saw this drawing by Swedish illustrator Olle Eksell which shows the egg in its midcentury setting at Tessin Park in Stockholm!  I don't know the name of this drawing or where it appeared...I found it on a website that now appears to be defunct.  If you have any information do please let me know. There is a new book on Olle Eksell (Olle Eksell: Swedish Graphic Designer ) being released in April...perhaps I'll find the answer there.
