To remember the generosity of His Majesty, a bronze statue was erected at the Plaza Mayor fronting the Manila Cathedral in 1824 where it still stands today. The plaza is now called Plaza de Roma to celebrate the elevation to the College of Cardinals of Rufino J. Santos, the first Filipino cardinal, in 1961.
The postcard above was issued in the 1920's with Plaza Mayor renamed as Plaza Mckinley in 1901 after the US President.
