Thor Annual #15 is the Thor chapter of Marvel's 1990 The Terminus Factor crossover, a five-part storyline that ran through the annuals of Marvel's flagship titles. Written by Roy Thomas with artwork by Rich Buckler, Gary Hartle, Mark McKenna, Mike DeCarlo, Ron Frenz, and Gary Barnum, the issue features appearances by Thor, Terminus, and other Marvel heroes as they confront the return of the cosmic menace.

This professionally graded CBCS 9.8 White copy represents a virtually flawless example of the issue. While not a major key, it is a desirable high-grade copy for collectors assembling premium Thor runs, Marvel Annual crossovers, or registry-quality late Bronze/Early Copper Age books. The striking cover featuring Thor battling Terminus makes it a standout display piece for fans of classic Marvel artwork.
