Graveyard misprints

I have these 2 Graveyard misprints.
Why misprints? They are a bit out of register and the black is dry in several areas. 
These are both "mistakes" that I really like. They give a very cool character to the print. The problem is that I can't offer them as proper prints because... well.. they are not proper.
The poster is a 3 color screen print on heavy sand color paper, 50x70 cm.
I have 2 copies.
