My Grail-Quest

Year after endless year, I have relentlessly searched for this grail page... high and low, from continent to continent, tirelessly and doggedly. As it was with noble Ahab before me, this implacable, remorseless quest can only conclude one way. Yet the hunt animates my waking hours, and haunts my dreams with visions of finding Amazing Adventures #5, page 3... and with it, ultimate peace and final, blissful serenity.
While I have followed the serpentine trail of previous owners from one soul-crushing dead end to another, I have never shared any of the results of my exhaustive detective work... until now. If any of the primary evidence revealed in this photographic ownership chain casts a light on The Shower Page's current whereabouts, I beseech you not to reap the spoils of my efforts for yourself, but to assist me in this glorious quest, and by your good deeds, shine a light in a weary world!
