Is that Groucho?

I’ve been scanning and uploading images from an old book a friend loaned me.  It’s a German humor magazine chock full of public domain pictures.  Delightful stuff (except for the racist images).  But the picture below caught my attention because it looks a little bit like Groucho Marx is standing around in the background.

And finally, I can’t help but think this is an image about sexy dreams.  Or acid trips.  Or both?
