German Post paper form shows HTML font tag

Something fun for a change: This morning I had one of those "you were not present when we tried to deliver something to you, please come to the post office to pick it up" cards in my mailbox.

However, as the scan of this very card shows (check for the red arrow), they inadvertently show half of a HTML FONT tag for the font "HELVETICA" on the actual printed card. I wonder how nobody could notice ;)
