few years ago a guy i worked with brought in this huge book full of artwork half of which was really amazing sci fi and fantasy artwork, everything from oil paintings to digital works.

i believe they release a new one every year that features artwork released that year and there's a few volumes

i can't for the life of me remember the name of it. anyone have any idea? i'm pretty sure it was only a single word
