Well dunno abt the cover but maybe this is the book you’re lookin for
It was even published in 1977
Yes I agree. Seems like it. Thank you again… 
One thing I’ve not seen mentioned here is that with old books sometimes the cover art and title is changed over time due to reprinting and translation, updates etc. so it’s possible that the version you are after is available but may look and be called something slightly different than you remember.
