El Tony Extracolor, also known as El Tony and El Tony Extraordinario, was an Argentinian magazine published by Editorial Columba, with its first issue being printed in mid-1928.
Its 400th issue was of note to the Doctor Who universe for its printing of the comic story Daleks, invasión a la Tierra año 2150, a licensed adaptation of the feature film Daleks' Invasion Earth 2150 A.D..
This comic is especially notable, on account of it being the only known licensed Doctor Who story to be published exclusively in a non-English language - specifically, Spanish.
