Retro SF covers

Time to emerge from summer hiatus and for my first something new of the year some OLD 

I found some old SF paperbacks at a recent book fair 

yes a genuine ACE Double and an Aussie SF writer featuring Grimes 

Heres some more detail of the cover 

note the Hand painted Tones and the use of Drybrush ! 

I have a few more covers to show you soon !
