Hi Paolo, I don't know if this set is being released especially for the anniversary.
Regarding the last released Leblon smurf, I am not 100% sure but this smurf may have been released for the 40th anniversary. I know it had been released a year or two before I started recollecting and this would put the date near 1998?????
I have borrowed this pic from Xavier.
Anyone know when this smurf was released?
