Virtual Postcrossing Easter Meetup (Finland)

This is the second postcard from my new Finnish penpal whom I met through Postcrossing. This is a really beautiful postcard from a meetup, which is an opportunity for Postcrossers to meet in person to talk about their hobby and meet other likeminded people. But this one was virtual (of course) so I’m even more impressed that they were able to get so many signatures on the back! How did they do it? It’s really beautiful!
