When did he post that?

How can you tell that bleedman did that?

he posted it in December on a comic called brain dead & i know he drew it cause the comic was tittled Guest Comic: Little Girls and their Scary Needles & the author also said he did in his comment on the page + the little girl looks like Bio. he also did another one called Guest Comic: Green Herb + Red Herb= Abomination Herb
