Coast Path Art Card by Christina Carpenter

I am very pleased to have this card and will be framing it to put in our static caravan on the Dorset coast which is very similar to this view. One question I would love to have the artist answer though is how it was created. I can see lots of English words/text very faint behind some areas such as the path, hills and waves. Was it painted over newspaper or something similar?? Just curious. Can't stop looking at it. Beautiful!!

Having walked the entire South West Coast Path once and walking over half the coast path in the opposite direction the card is very evocative of the joy the coast path gives.
