The postcard shows another painting of Fernando Amorsolo entitled Atis & Lanzones, fruits that can be found in the country. I can only give the information about the fruits about the painting and not the location of the painting (private collection or museum).
Atis or sugar-apple or sweetsop is usually round, slightly pine cone-like, 6-10 cm diameter and weighing 100-230 g, with a scaly or lumpy skin. The fruit flesh is edible, white to light yellow, and resembles and tastes like custard.
Lanzones or Lansium domesticum fruit is covered by yellowish, thick, leathery skin. Underneath the skin, the fruit is divided into five or six slices of translucent, juicy flesh. The flesh is slightly acidic in taste.
