First I would like to thank you for your confidence of my rooting out answers, but in this case I'm afraid we will have to depend on the local Trinidadians expertise. :)
I only have pictures of the Methodist Church that was south of the large building on the southwest corner of Colorado and Arizona.
I do not have any photos of either of the corner buildings.
Perhaps if you specify which corner, SW or NW, of Colorado and Arizona we might get an answer. :)
