Oops – What the Dairy is Going on Here?

After visiting the National Gallery (see recent post) I walked up Whitcomb Street to the lbrary on Orange street where I was verbally abused by a mentally challenged man of the street. But that's another story.
The two-sided Dairy sign is still there...
But, er...

Top row 2009, bottom row Feb 2017

Perhaps the D fell off and had to be reattached...?
But it's upside-down!
Was it some kind of bright idea to get the verticals aligned at the front edge?
Why not go the whole hog and spin the R too?
