This First Day Cover features a souvenir page from the U.S. Postal Service commemorating Luis Muñoz Marín, the first popularly elected Governor of Puerto Rico. The page includes a strip of five 5-cent red stamps with an engraved portrait of Muñoz Marín, designed by Juan Maldonado and engraved by Gary Chaconas and Gary Slaght. The stamps are cancelled with a circular first-day postmark from San Juan, Puerto Rico, dated February 18, 1990. The page provides detailed production credits and a biographical summary of Muñoz Marín's life and achievements.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
