Postcard HU-218349

The members of the Facebook group "Postcrossing Hungary - no swap!!!" came together in Veszprém on September 30th and October 1st. It was the 29th meetup of the particular community.
We released 2 postcards to commemorate this event. This particular one is devoted to the second day of our meeting.
Both postcards were designed by my wife, Zsuzsánna Poór. The photos are hers, too.
As for this particular one, there is a mistake on its front side. The word 'Hungary' is missing in the grey field. Thus, it is a misprint. That is why, this postcard may become a valuable collectors' item.
