For good reason- looks like it'd be terrible to get into and out of. But everyone's 'seen' it- it's just a first position G chord slid up to a C. Sometimes it's useful to do that- and damp the open strings. The middle part of A Day in the Life is just sliding an open E major chord up fret by fret and playing all 6 strings. Calypso music uses the Cmaj or C7 open chord shape slid up to make IV and V chords with the open strings damped. Not too smooth with that G shape, though.
