here's a sign from the belgian design museum. you'd expect it to be good, but this is most excellent.

they had two giant posters of airport signage on display in a special exhibition but there was no photography inside which was a shame. you'll just have to visit yourself.

not visit yourself. visit the museum. visiting yourself would be slightly odd. unless you were a timetraveller. but even that would be odd, unless you were going forward in time in which case you'd already know you were a timetraveller and it would be less odd.

but what is this ? a cat with its eyes closed drinking through a straw ?
