The Pornographic drawing will never die, whereas erotica is more vulnerable; there is something there that links pornography to folklore; although most of folklore is parochial and leans rather toward kitsch and erotica.
Folklore is not sustained by universal interest, but it is respectfully preserved. Not every culture has pornographic folklore, but most have contributed to erotic kitsch. Is pornography a genre that will always transgress, or may we see it posted publically some day? If pornography went public, would it be the end of it, and would it become as vulnerabble as erotic art?
