@vayolene,
annoyingly, people keep using Scott numbers for Europe and colonies stamps and do not post pictures

. My guess is that he is talking about the 21-1-2011 materials set from booklets and issued in sheets on 24-1-2011. One stamp is a material from Polynesia - probably Yvert A514 & A514A -, the other that from Japan - probably Yvert A520 and A520A -.
