I found this very old rollercoaster a very interesting structure. The lines, shapes and contrast are arranged to create a cohesive and meaningful composition. 
 
The original was hand painted in detail in gouache paint then printed professionally by my local printers onto 170 gsm gloss paper.
It comes in a size SR A3 (slightly larger than A3) to give you a white surround to enable you to mount and frame it easier.
I also do A4 size prints with a white border for more affordability.
