The processes p{bar p} {yields} {ell}{bar {nu}}{sub {gamma}} + X and p{bar p} {yields} {ell}{sup +}{ell}{sup {minus}}{sub {gamma}} + X ({ell} = e, {mu}) have been observed using the DO detector at the Fermilab Tevatron Collider at {radical}s = 1.8 TeV. The observed signals in the electron and muon decay channels are used as a probe of the WW{gamma}, ZZ{gamma}, and Z{gamma}{gamma} vertex couplings. By comparing the event rates and shapes of the photon ET distributions with theoretical predictions, 95% confidence limits are obtained on the WW{gamma}, ZZ{gamma}, and Z{gamma}{gamma} vertex coupling parameters.
