It is argued that if strings are responsible for many of the quasar lens systems and for galaxy formation, then nearby string loops should produce a substantial number of groups of near-identical twin galaxies with near-constant separations. Groups with a few twin members should present a striking doubled appearance and should be easily recognizable. One example of this type of object (found serendipitously in a CCD frame of a distant quasar) is discussed which contains four such identical twins with separation from 2.0 to 2.5 arcsecs, lying in a region about 20 x 20 arcsecs. Morphologically it presents the appearance expected from a string-lensed region. However, the accurate velocity splittings between the pairs which would be required to distinguish this from a chance concatenation of binary pairs are not yet available. The latter is an implausible explanation but may be possible if there is a very high incidence of binaryism in a substantial fraction of distant groups.
