Promoted from a comment left by great and good FotB RoadRich, talking about bad public art:
All it evoked for me was ‘someone put up traffic signs and the dumbass forgot to add the letters.’ They have a DOT standard look to them.
…specifically Special Route Markers meant to be Guide signs (blue with white accents) in Chapter 7 of TxDOT’s Sign Guidelines and Applications Manual. Examples exist on page 7-14 (Special Route Marker), page 7-24 (indicating Emergency Services facilities), 7-46 (Historical Markers), and 7-51 to 7-52 (Rest Area).
If that hasn’t gotten you all excited about roadway signage you can also look up Manual on Uniform Traffic Control Devices (MUTCD), currently in revision 2 of the 2009 edition. Ooo, page 301 embodies the spirit of ‘All General Service signs and supplemental sign panels shall have white letters, symbols, arrows, and borders on a blue background.’
I’m such fun at parties.
You know where I’m going with this, don’t you?
