This is a POTF Pop Up R2-D2 First Shot.  First shots are usually identical to their production counterparts as they are technically the first figures to be put through the mass production process using the regular steel molds.  The only difference between a First Shot and a production figure in most cases is production figures have copyright markings on them.  As shown below, this figure does not have the production copyright markings.
