This blueprint is 21cm by 30cm and made from a analog photograph.
Every cyanotype is different so impossible to make exactly the same copy. This is in my eyes also the beauty of a blueprint. The print is made on cotton paper from India.
This is a listing of 1 print but 1 picture contains 4, just to show that it could be nice to frame a couple of blueprints together.
Feel free to ask me for more info.
