This card was sent by Sylvie (Sylvie-Bouneweg) as an official card, and was favorited 6 times in my favorites wall. 

Grand Duke Henri, Grand Duchess Maria Teresa, and Prince Felix

This was a former favorite, an official card sent by a Dutch :)

Received this from Natalia (NatalySh), favorited 4 times.

Received this from Annie (annie19960430) from Taiwan. This card was favorited 12 times.

I have received other interesting mail and cards too, but too bad, we won't be able to connect our laptop to the scanner. (due to wires)

I'll probably take pictures next time by camera phone.
