Hello - I recently purchased this pair of "vintage" bottles. Initially I was unsure if they were vintage or just made to appear such. As I have studied them I do think they are older but as I have little experience in this area of collecting thought I would solicit views of true experts. They measure just under 12" tall; they are made of green glass covered with a vinyl coating that is decorated with portraits of a Native American man and woman. The decoration appears to have been created using lithography. The bottles are similar but not identical. There are some markings on the underside - primarily numbers (see photo) Welcome any/all views/opinions. Thanks
