Someone could think that these are not proper urban sketches since they were not made on location but at home (about 650 km far). Some other could think they can be accepted since they were actually made from life, using images taken with my eyes about 40 years ago and saved in my mind until today. No photos (I haven't), no invention (I guess).
These are a pair of spreads of my scribble sketchbook, the one I use everyday, I almost never take out from home and that has not even one drawing from life (from TV at the most). It has just sketches for work, experiments and silly things as this series of images from memory of the house of my grandparents, a place I used to go in remote times and that was demolished in the first eighties to build apartment blocks.
There are some images at a legible size on flickr for daring curious (in spanish, sorry).
