Screenshot of Tim Berners-Lee’s Next workstation screen from, I would guess, early 1990.

Update: Hmmm… James Cridland did some digging and came up with a directory listing which assigns the date 7 June 1994 to the image. This doesn’t necessarily date the screenshot, though. But if it does, then the image certainly isn’t “the very first Web browser”, as the headline on this post suggested, because Mosaic was released by Marc Andreessen and Eric Bina in the spring of 1993 and there were certainly browsers running on Tim Berners-Lee’s NeXT workstation in CERN way before that.

In any event, the first browser was a text-browser like Lynx rather than a graphics-based one like that shown in the screenshot.
