Absolutely NO VECTORS! I don’t know if you, dear reader, are super familiar with logo design (or graphic formats, in general), so please allow me to explain a thing (those who ARE familiar, please bear with me).
Short definitions of 2 main graphic file types, raster and vector:
raster - images made up of pixels. if scaled up too much, look like crap. vector - images made up of... well... math. infinitely scalable.
So, a good, usable, adaptable logo will ALWAYS be in vector format. This poor poster obviously has very strong feelings about... something. Something that he thinks is called “vectors.” Probably he means clip art? Or abstraction? Straight lines? I don’t know.
Or maybe he just wants his logo to look like shit when it’s blown up to be a billboard; people are weird.
