I've designed large format prints for various marketing and advertising
firms. These large format prints are used in booths, exhibitions or even
in bazaars. My record is 23 foot by 14 foot mural (7 meter by 4 meter)
wall poster cover wallpaper style. All I need from you is a
similar design to what your poster design to look like, royalty free
image(s) that you own/bought and your logo.
Price depends on the size of the poster/print/mural. Starts from $5 and up for 1 item, I can do many items all at once.
