My third Miserable Monday installment! (part I, part II)
Evil lurks behind purple clouds — a mascara-eyed man be-speckled with sparkling stars leers from the purple haze (the aphrodisiacal gases of paradise?), a goggled hero clutches his chest due to the horrific color palette sheeting towards them (a purple god’s purple tears?)(“O no! Run! Shall we run from the purple and green atomic rays?”), and real humans aren’t purple, so, the androids must be — to blend in with the real humans? or, are all humans purple but only androids see the purple spectrum? Serious questions.
No wonder the cover artists aren’t credited!
Enjoy, and try not to laugh. Remember, the artists are asking serious questions.

The horror! The horror!
I know! The guy in the first cover looks like Apophis from Stargate.
lol… what I can’t figure out, is why they announce the non-human aspects of Mr and Mrs Android as though we’d be surprised!
Hehe, all three are terrible/pain inducing. And it’s not just the colors!
Yep, those are some hideous covers! Especially the first and third ones. I think I’d run screaming from those before I would ever pick them up to read.
