Best I could do was 16. So, I decided to cheat and made it to 28. I got to 25 and got tired f googling the anwers. Even googling, I missed a couple just placing them wrong or they had the date a year off here and there. I only had one miss left at 25 when I stopped cheating.. I started placing them best I could at that point. I got to a Van Gough painting and had an idea but I also had about 10 things already in the late 1800's. I had no shot without cheating and let it die an ugly death. I think I am done with it.
