Swamp Thing # 59 has been hand signed by Bernie Wrightson (1948-2017, Swamp Thing Co-Creator) and John Totleben (Inker) at the Baltimore Comic Con 2015. Alan Moore changed comics with his innovative writing on Swamp Thing. Combined with a detailed and mood setting art by Steve Bissette, John Totleben and Alfredo Alcala among others, Alan Moore's Swamp Thing led the way for more mature stories in main stream comics that would eventually lead to DC's Vertigo imprint. The signatures were witnessed by a Brooklyn Comic Shop representative. This comic comes with a signed Certificate Of Authenticity (COA).
