The Home Run Twins together again. Dual signed baseball has the mighty Mickey Mantle on the sweet spot in 6.5/10 black ink. His partner in crime Roger Maris is on a a side panel in very strong (8/10) blue ink. Official American League (Brown) baseball has mild toning but still grades EX+. Grading here is very conservative as we like it to be. PSA/DNA LOA is included attesting to its undoubtable, undeniable authenticity.
