It's not hung where direct light can hit it, or where there's strong lighting, and the flash doesn't do so well against some of the black paint. No flash and a long exposure time might do the trick, so if I have time and the opportunity today when out, I'll see about getting a tripod.
Admittedly I'm not familiar with the artists of my mother's home country. My father, an American who had initially visited the Philippines and then returned for business (and wound up staying for over 20 years), paid 3000 pesos for it in the early 1970s. When we moved to U.S. in 1983, after he decided it was time for him to repatriate, it was one of several paintings we couldn't bear to leave behind.
It's still not terribly valuable, mostly since Buenaventura produced so much, but it's highly unusual in that he glued pieces of wood onto the canvas, painting over them for a raised effect. He did this for the calesas, horses, drivers, the house on the right, even the calesa wheels in the very front. I've never heard of this technique used anywhere else.
