This 1871 illustration of an "eight-armed cuttle-fish" has become the unofficial mascot of Pharyngula, Professor PZ Myers' science and atheism blog. Now this handsome creature (the cephalopod, not PZ) is available on a very official Pharyngula t-shirt.
Screenprinted in navy blue ink on an Anvil 100% cotton jersey tee in storm grey (for men/unisex) or Caribbean blue (for ladies).
Fits true to size for both women and men.
Thanks to Maki Naro for help in making the woodcut screen-printable!
