Recently, a distinct shadow mechanism was proposed by Wang et al. from the asymmetric thin-shell wormhole (ATW) [X. Wang, Phys. Lett. B 811, 135930 (2020)PYLBAJ0370-269310.1016/j.physletb.2020.135930]. On the other hand, Gralla, Holz, and Wald's work [Phys. Rev. D 100, 024018 (2019)PRVDAQ2470-001010.1103/PhysRevD.100.024018] represented a nice description of photon rings in the presence of an accretion disk around a black hole. In this paper, we are inspired to thoroughly investigate the observational appearance of an accretion disk around the ATW. Although the spacetime outside an ATW with a throat could be identical to that containing a black hole with its event horizon, we show evident additional photon rings from the ATW spacetime. Moreover, a potential lensing band between two highly demagnified photon rings is found. Our analysis provides an optically observational signature to distinguish ATWs from black holes.
