about public domain art

i discovered this year googling around that there is a tremendous amount of public domain art on file in our public libraries ... i found a wonderful source in the new york public library ... i was looking for ideas this weekend and decided i would like to do small bouquets the type that would look good on pillow cases ... i would think all the major cities have similar files i.e. chicago, la, atlanta, etc. ... trust me its worth checking out ... for those of you digitizing it will keep you very busy ... when you get to their site just search public domain art
