Following the announcement of increased gamma-ray activity from the blazar TXS 1318+225 by Fermi LAT (Torresi et al., ATel #4609) we have checked the archival data of the MASTER robotic network. This object (SDSS J132111.20+221612.1 u=19.49 g=19.08 r=18.72 i=18.46 z=18.16) was detected on the MASTER-Amur survey image of 2012 Nov. 28.878 UT at unfiltered magnitude 16.56+/-0.19. This is the brightest state of TXS 1318+225 as observed by MASTER. Object was fainter than 17.1m on 2012 Nov. 16.890 UT image from the same telescope. The low state unfiltered magnitude is about 19 mag from MASTER-Kislovodsk arhive data.
