I draw sometimes some urban sketches of Berlin on a double page vertically or horizontally of my sketch book.
That’s why the format of this illustrations are a “standard” poster: VERTICAL: 23 x 56 cm/ 9 x 22 inch
PANORAMIC: 54 x 19,8 cm / 21.26 x 7.8 inch
Material: I choose a special paper because I want to have a nice aspect for my images. HP Photopapier Matt 180 g/m2 (615 lb)
P.S.: If you want, I can print for you a bigger poster (possible until 3 meters). If you are interested, send me please an email at email@example.com
