Query: K* photoproduction off the nucleon: gamma N --> K* Lambda   We study the photoproduction of $K^*(892)$ vector meson from both the charged
and neutral reactions, $\gamma p \to K^{*+} \Lambda$ and $\gamma n \to K^{*0}
\Lambda$. The production mechanisms that we consider include $t$-channel $K^*$,
$K$, $\kappa$ exchanges, s-channel nucleon diagram, and $u$-channel $\Lambda$,
$\Sigma$, $\Sigma^*$ diagrams. These could constitute important backgrounds for
future investigation of ``missing'' resonances that can be searched for
especially in these reactions. The $t$-channel $K$ meson exchange is found to
dominate both reactions. The total and differential cross sections are
presented together with some spin asymmetries.
