Technically, these drawings are turned inside-out. You cannot take a black and white drawing, invert te colours and print it on a dark background. If you try anyway, the eyes of the animals become an eery white and the shadows are all wrong.
I made these drawings specifically for printing on dark coloured T-shirts. I also made similar, but less detailed versions for engraving in glass mugs. Some of these are available for sale through our Etsy shop: RememberNature.
