We were introduced to Alexandre Louzada, the creative director at Portela. Alexandre has worked creatively with Samba Schools since approximately 1985. He showed us all of the amazing costumes he has been working on with at least one other draftsman by his side. He also designed the floats for Portela, but again, no matter how many different ways I asked, I could not see any drawing of them.
This was my first realization at how certain information will not easily be relinquished. Unfortunately, it is clear that the main information I am looking for will take a lot more work to before it is shared.
