About the Company

Former state-owned telegraph, telephone and telecommunications company Portugal Telecom, PT for short. It consists of a number of filial companies, mostely sharing the same logo (and with similar flags).

White Flag

Its corporate logo is, since the mid-1990ies, made up of four squares, two containing a disc each, the other two respectively a sans "P" and "T"; in contrasting colors, usually dark blue and orange, with white letters; the squares usually placed 2+2.

It is a very clever logo, masterly applied in numerous variations (links to on line example images in other sites):

These applications include flags, of course — some with full company logo and lettering on white, for any of the companies of the group, but there is also a simple logo-on-white, no-lettering flag (here at the company headquarters).

White Flag with Inscription

I was told by someone at an advertisement agency I worked to a couple of times that these two squares (blue disc on orange for "P" and orange disc on blue for "T") actually are part of a latin alphabet set, created by the brand designers (but of course these two were made first and their similarity is not coincidental). Other "letters" of this set are sometimes used in PT advertisement and stationary material, but seldom with textual meaning. I never saw these discs on squares in other colours used on flags.
There had been obsolete manual and a web version of it. At (p.3) the relative sizes of the square, disc and gap are given: 8, 5 and 1. (I'll send tomorrow a corrected version of .) No mention in the manual to the other "letters", (p.9). Quite unusually, a flag design was not forgotten by the authors of the company's corporate identity: On a flag design is given, the one with logo on the top hoist and lettering along the bottom, i.e., not the more usual white with big logo centred: with ambiguous specs.

Portugal Telecom Multimedia red Flag

At obsolete page, however, the flag of PT Multimedia is red with lettering and logo, the latter being white and the former encased in the usual white edge, with unchanged colours. (typeface should be PT Bliss Bold; I used Trebuchet and Tahoma for lack of it). The red flag of PT Multimedia, does not seem to follow these in what concerns position and sizes of the logo and lettering, seems to contradict the the PT corporate identity manual also in what concerns logo usage on coloured background.

Blue Flag

The "clever logo" I praised, was changed, just short of replaced, by a single light slightly greenish blue rounded corner square outline enclosing the two discs and the letters "PT" (maybe suggesting a generic socket?), in May 2009. (This new styling of the same basic arrangement does not allow for horizontal and vertical logo variants, as the previous one had prescribed as alternatives, although those had no use on flags, as far as I know.)
This change promptly affected flags, which are now plain of the same light slightly greenish blue with the logo centred thereon, its outline suggested by shadowing shade variation on the logo.
