This is Advanced Dungeons and Dragons Fantasy Adventure Module A4, Product number 9042 - In the Dungeons of the Slave Lords. I bought it from a vendor at GenCon in 1990. It is still in the shrinkwrap. I haven't opened it since I bought it. The shrinkwrap is showing signs of aging, but the module still looks to be in very good or better condition, but since I bought it from a vendor there, I am listing it as used.
