Vanishing sun on the 25c 'Servicio Oficial'

I have shown these before for the regular issue. This variety is found on one of the 1E3 printings. Here are two specimens showing a vanishing sun. It seems that when the variety was listed as 'missing sun' high magnification and digital filtering were not available. Once these two techniques are used, it is clear that there are a few dots for the rays of the sun that are visible.







Here is a second specimen.
