NAVIERA DEL ODIEL S.A.

Lista Oficial editions of 1961, 1962, 1966 and 1972 and the earlier Untzidien illustration show black letters and a grey funnel base.

Brown 1995 instead gives white letters and an entirely black funnel, with the flag’s white lettering confirmed by the company website. In response to Rosanoski’s enquiry, Astui reviewed photographs: most lettering was indistinct or seemed dark, but one view clearly showed white letters, and all funnels were entirely black. He therefore favoured Brown’s version.

Rosanoski leaves open whether the discrepancy reflects a change or errors in earlier sources, cautioning that website artwork may also take liberties.
