  We present a new sample of 84 large angular size radio galaxies selected from
the NRAO VLA Sky Survey. Radio sources with declination above +60 degrees,
total flux density greater than 100 mJy at 1.4 GHz and angular size larger than
4 arcmin have been selected and observed with the VLA at 1.4 and 4.9 GHz. The
radio observations attempt to confirm the large angular size sources and to
isolate the core emission for optical identification. In this paper, the first
of a series of three, we present radio maps of 79 sources from the sample and
discuss the effects of the selection criteria in the final sample. 37 radio
galaxies belong to the class of giants, of which 22 are reported in this paper
for the first time.
