This is all museum quality, Crescent,Peterboro,ragmat..Matboard. Most of the blanks are between 8x10 to just under 11x14. I dont really use anything below 11x14. ideal for small photographs/drawings..Also theres about six large precuts and a few smaller precuts that just didnt meet show standards, fine for general display. I generate quite a lot of this over time..(im keeping the bin :)..) thanks
