I came across this company when I was on craigslist of all places, and they seem to be a great resource for hard-to-find prints, most at really affordable prices. Of course I had to pick out the one that's the most expensive—the above print is a rare Andy Warhol original lithograph titled "Marilyn Monroe I Love Your Kiss Forever Forever", published in 1964 for 1 Cent Life, in an edition of 2000 ($1,195). The print shown below, also an original lithograph (printed on wove paper), by French artist Andre Brasilier "Le Cadre noir" was printed in Paris (also in 1964) by the legendary atelier of Fernand Mourlot ($175).
