Vintage Russian Poster, USSR Soviet Union International Women's Day by Juozas Galkus 1968 Art Print

I ordered this poster in X-Large because I assumed if the shop was offering it at that size, then the original poster must be a large enough size to have been scanned at a resolution big enough to print in X-Large. Unfortunately it seems that the original poster must be smaller, and when they sent out X-Large they expanded the image beyond its resolution which resulted in a blurry and pixellated poster. This is normal of course (you can't print an image beyond its resolution and expect it to be clear), however what is frustrating is that the original poster size isn't listed on the shop so that I could have known this would likely be a blown-up, blurry image. Had I known that I would have ordered a smaller print which would better match the resolution of the original. My assumption if a shop is offering X-Large it means the resolution and DPI is high enough to sustain that size. I can't comment on the quality of this in smaller sizes, I suspect they look fine at those. I would very much recommend reaching out to the shop first to ask what the original scanned size of the poster was so that you can order accordingly. Thanks
