There is a new stamp avi being shown around the boards today and to get it you need to view Faerieland page with it completed and you get this event:
Seems the JS are releasing a new avi but messed up the coding and put it to Faerieland and not to Skenkuu. I can confirm this works and does increase your avi count.
Get the avi now while you can (if you have completed FL that is) or stock up on Shenkuu stamps as they are going to increase in value very quickly.
DOES not need to be FL it works with any FULL page. Also there is a new Shell Stamp avi.
