Mills and Boon romance cover - 1979 - 'The Edge of Spring'

Original artwork, paint on thick art board, by Frank Haseler (1928 - 1996) for the romance novel 'The Edge of Spring' published first in the UK in 1979. As with many of these Haseler pieces the back of the board indicates that it may also have been published elsewhere (see additional images below main image).

I have had a guess that this painted in gouache, but I could be wrong!
