The core-dominated quasar 0106 + 013 was observed with a global VLBI Array at 6 cm in 1986 and 1988. The radio structure changed dramatically between the two epochs, from barely resolved to well separated double with flux ratio 3:2. Identifying the changes with east-west movement between two components, the proper motion is found to be 0.20 + or - 0.5 marcsec/yr, which corresponds to v/c = (8.2 + or - 2.0)/h (for z = 2.107; H0 = 100 km/s Mpc, and q0 = 0.5). The speed is typical of superluminal quasars.
