It doesn't look like Scott numbers have been issued yet. I looked at the Scott New Listings to date but these aren't shown.
Hello Philippe! This was the last set of 2016: Issue: December 19, 2016 Children Art Contest - Sane feelings and values Probably will appear in 2018 or 2019 Scott. Regards! Rodolfo
Stampworld is more up to date than Scott for recent Argentina issues.
Re Stampworld Yes Al, I use their numbers for everything newer than my 2011 Scott catalogs. No matter how new a stamp, I easily found it in Stampworld.
