I'm new to the world of the history of vintage posters. Being a graphic designer I have always admired how amazing they are. I received these from a friend and was hoping to get some more info on them. I have done a little research on them but have had trouble locating two of them Operation pacific and Masterson of Kansas. Masterson is my favourite, the red, the image and typography is amazing. Pity a mouse has got to it. If anyone can shed some light that would be amazing.
