Hola Natalia :)
Briliant idea from you once again :)
I honestly, cannot understand this hate to CTO. They helped many of us in our beginnings. And some CTO are cancelled to order, but sometimes, this makes stamps even more appreciated.
As you mention http://100stamps.club/stamps/ES-1015 , here I make you sure stamps are not junk.
This member asked some very specific questions and we prepared stamps answering to topics of this member. He has not the right to fine low rate, specially, to a 6 years old kid. Sorry, but I keep insisting on this. This is not fair and this does not help to promote our hobby in future generations. Nachopl sent more than 100 stamps, in perfect conditions, matching member wish list (which is not mandatory finall). For all those members making his own rules, I suggest to go to an auction before rating 1 or 2 star to people who took time in sending you good stamps and SPENDING MONEY on it.
Maybe we should think in a better and positive use of "low ratings".
CTO ??? They are also stamps. Not circulated like mint stamps, but stamps finally. Some CTO have much more beauty than some regular stamps. I dont think we can avoid CTO, they are a part of the philately world too.
Take a look and read my new profile :)
