Under Marswood

another fine example of older style SF paperback covers 

This one is by Darrell Sweet 

Retro SF covers Two

Unfortunately no artist credit was given for this 1969 paperback edition 

Another great SF book cover

# bookcover #SF #threecolorrule 

Another great example tho my photo taken with the mobiles not so good is this elegant cover for The Rise and Fall of D.OD.O. Just 3 colors black yellow white ! and a reference on the cover as to how  Schrodingers Cat leads to time travel and science battling magic!
