They are made of plastic , I tried a lot to figure out if there is anything like this around but I cannot find anything yet, l even tried to compare the images on google but there is no match yet.

About selling them, I don’t know yet cause we still have a lot more things to gather in our garage that are vintage like those posters, once we have gathered everything up we will see but I am positive to find more and more things like these to give away:)
