My version of your 'abstract red one' is a black and white one with lots of wavy lines that was in the Pump Room in Leamington Spa. I was unemployed and pretty severely depressed at the time (but too depressed to realise it) and I used to go into the Pump Room at least once a week, just to look at this picture.

I remember the artist was a woman but that's about all I can recall.
