That's all said in the auction description.
No, no it is not.
Your description states:
The stamp was professionally repaired in the right bottom quadrant as you can see from the pictures
It doesn't state a good percent of the original stamp is missing and was drawn in by hand.
In the world of US taxpaids, repairs using pieces of other like stamps to make a whole stamp are pretty normal and is an accepted part of revenue collecting. I would put forth not many folks would be happy with a US #1 with pieces of 3 different stamps repaired together, however skillfully.
That is considered a faulty stamp. Not turning my nose up at it as I would rather have a repaired copy from a collection I purchase than have no copy at all, but I wouldn't search out a faulty copy unless it was truly rare and I have zero expectation of owning a normal copy in my lifetime.
Keep in mind some collectors chase the various forged examples as well and some are worth more than the original stamp. Others will have to speak to whether that is the case for early Brazil.
