Saturday Fun Activity: Where IS this?

     This struck me for several reasons, in the few seconds after the el car doors slid open.
     The colors, first of all: light steel blue tiles with a reddish orange trim. Quite smart, for public transit.
     And then the whimsical typeface on "LOOP," the odd little split between the "LO" and the "OP," almost rendering it into a different sort of word. There was something sweet about it. 
     And oddly, there is no stop called "LOOP" on the el—I know it's officially 'L', but that looks ugly to me. If "el" was good enough for Nelson Algren, it's good enough for me. The CTA is going with 'L' now, officially, but it also created Ventra cards and we'll see how long those last.  Better to stick with the old standards.
     Sorry, where was I? Ah yes, so there is no "LOOP" stop to the el. This signage, though whimsical and perhaps even helpful, in a rough kind of way, won't tell you what station this is.
     Where is it? Googling won't help you here—I checked. You'll have to have just noticed it, as I did, which means you have an eye for design, and thus might appreciate one of my super-rare blog posters, which I will send to the person who correctly identifies the line and station this is. Post your guesses in the comments section below. Good luck.
