I penciled these layouts for "Quest for Dreams Lost", a one shot benefit comic (a fundraiser for the Literacy Volunteers of Chicago), back in 1986 or 1987. "Quest" was published in 1987, with all proceeds going to aid the LVOC. A number of other independent comics creators also provided stories featuring their characters searching for famous artifacts associated with literature. In this case, the Turtles were looking for King Arthur's sword Excalibur.
If memory serves (and I offer the caveat that I have not looked upon the finished work in many years), I believe Ryan Brown did the inking. -- PL
