Two more...
These were both efforts to try a different composition with a couple of different cover designs. Anyone who grew up on hold books will recognize the first design as based on that of Pan books from the mid 50s through to the mid/late 60s. The second was partly inspired by one of the designs used on Mike Shayne novels - I deviated quite a bit but drew more on the use of the gothic font - this one is League Gothic, which I found a close enough approximation.
