I'm currently sorting through my Brazilian stamps. I haven't worked out how to read the Scott listings, however. If you look at this example (see scan below), it doesn't specifically state that the DeGaulle stamp is unwatermarked, which it usually does when this is the case. So it's watermarked. But how are we meant to tell which watermark it has? Since it is watermarked, why does it only say that the JFK stamp is? This creates the perception that the De Gaulle stamp is different from this point of view. In fact, both stamps have the same watermark (267).

So why does it say only sometimes that the stamp has wmk 267, while saying nothing about others that have the exact same wmk?
Is this a problem that affects the entire catalogue or just the Brazil pages?
