It is called Philaclassic
http://philaclassic.blogspot.com.br/
It is published from Brazil, and in Portuguese. (Google Translator makes short work of any language differences, though.)
Rubens has started with Aden, and at this time appears to be adding a country a day. As of Sunday, he is already up to Algeria.
And Rubens includes a list of stamp spaces in the Steiner (Deep Blue) album, with those that he has in his collection marked in red.
It does remind me a bit of my own blog which covers the same era, and in somewhat similar format. So naturally I like it. ;-)
And Rubens illustrates some nice stamps. I've been unable to find any stamps from La Aguera - and the "La Aguera" post shows a whole set. ;-)
And we have similar organizational choices- collecting with the Scott catalogue, and using the Steiner album (Deep Blue).
I will be following the blog with much anticipation.
Check it out!

Update (January 9,2013): Sadly, the Philaclassic blog appears to have gone private, with no public access. If the situation changes, I will update further.
