Urbansketchers in Lisbon

I was lucky to be in Lisbon when the Urban Sketchers meeting happened in Lisbon.
I joined them to scketch the Terreiro do Paço.
However, after leaving my sketchbook for some days in the car, at the sun, the heat started "eating" my drawings, the ink vanishing...
I got them on time to save part of the drawings... but this is all I have now...
