Lou

I have a set of 4 prints that depict a stagecoach journey. They are signed Pierre Pinsard. The Pinsard is difficult to read so the name may be something else. Now, I find there is a print maker named Pierre Pinsard who was born in 1906 and died in 1988. However, these prints are very different in style. These prints have been in the family since the 1930s. Can anyone help me out with identification of the artist? Could it be the same man at an earlier point in his career?

Thanks
