Beginning today, we are inviting all designers and creatively inclined supporters to submit designs for Mikhail Khodorkovsky’s 50th birthday card. The creator of the winning design, which will be announced on May 15, will receive a copy of Khodorkovsky’s memoir “Putin’s Prisoner” signed by his son, Pavel Khodorkovsky. The winning design will also be featured as part of our campaign to gather signatures and birthday messages from thousands of supporters worldwide, which will be mailed to Khodorkovsky’s prison camp in Karelia.
