No .aux file was supplied.  They just gave us a .tif and a .tfw which were
in the same directory which means gdalinfo was run against both.  Based on
the limited information that was supplied the only thing that I can think of
doing at this point is to find all the EPSG codes listed under Guatemala and
running gdalwarp against each and then displaying each within a mapping
application to see if it accurately displays within Guatemala.
