IMHO, I think this is a genuinely old photo, not a reproduction of any kind. I look at the imperfections that age imparts to a photo and the presentation and that makes me believe the photo is old and original. That being said, I have seen many a print like that in antique stores and in my estimation your photo is from the 1900s. I cannot pinpoint what decade, I'll leave that to the more knowledgeable posters here. Good luck, though...
