Postcrossing-themed stamps
In 2011, the very first Postcrossing-themed stamp was released by PostNL, and since then more than a dozen other countries have followed suit, with some having released multiple different Postcrossing-themed stamps over multiple years. While the majority of these stamps have been launched in partnership and celebration with the Postcrossing community, some countries have released unofficial stamps portraying the Postcrossing trademark without approval of the Postcrossing organization. All stamps officially backed by the Postcrossing community are posted on the Postcrossing blog and tagged with 'postcrossing-stamp'.
