  We report on a VLBA imaging study of the nearby bright southern blazar PKS
1921 - 293 (OV - 236). High resolution VLBA observations, made at four
frequencies (5, 12, 15, and 43 GHz) over the period 1994 - 2000, have revealed
a strongly curved jet extending out to about 50 parsecs from the presumed
central engine. Two epoch VLBA observations, each simultaneously carried out at
both 5 and 43 GHz, show a large position angle difference of 51 - 67 degrees
between the jet emission at 5 and 43 GHz. Although the core of PKS 1921 - 293
has one of the highest brightness temperatures measured in any compact radio
source, unlike other bright blazars it is not a source of gamma-ray emission.
However, there is evidence in these images for superluminal motion within the
central region (a few parsecs from the core) and within the north-east diffuse
emission region. In all six-epoch 43 GHz images, two equally compact bright
components within the central parsec are seen.
