arrow signs collection
Near the start of old Route 66 in Oak Lawn (a near suburb of Chicago), Petey's pulls you in with the tantalizing promise of a yellow martini containing a sunk cherry.
It's not clear whether the arrow here is offering directions to the parking lot or just advertising that there is, indeed parking available. The secondary use of the arrow to subtly provide structural support for the right half of the sign is very common in arrow signs.
