Created a year before Vitalis died, the Tres Marias was largely inspired by the women the artist encountered during his stay in Iligan city; done in a studio that was set up by his nieces — the year 1988 is dubbed as Vitalis’ most productive period. This productivity resulted into two exhibitions: Galaxies in 1987 at The Metropolitan Museum of Manila, and Coconuts in 1988 at the Finale Art File.
