If you have a two foot square space that needs to be brightened and always uplifting at a glance, Mr. Martin's art is does it.
Martin would have been unusually fortunate to have an education beyond the fourth grade and when he began painting he had probably left home at 12 and was seeking a means of eating and clothing himself. Look at beauty he learned to express.
Note in first blow up the bird nipping Snapper's ear gives Snapper some depth in dimension. The second picture of a bird starting to nip Snapper continues this illusion. The third bird has taken the top of Snapper's body in his beak as if snapper is a cardboard prop. The fourth picture shows the gouging damage to the painting.
