New low-frequency radio maps of 3C388, which show that the morphology of the source is consistent with previous observations at GHz frequencies. Top: LOFAR 144 MHz map with contours equal to −3, 3, 5, 10, 20, 50, 100, 200, and 500 × σ₁₄₄, where σ₁₄₄ = 5 mJy beam⁻¹. Bottom: VLA 392 MHz map with contours equal to −3, 3, 5, 15, 40, 150, 500, and 1000 × σ₃₉₂, where σ₃₉₂ = 1.5 mJy beam⁻¹. Colour-bars are expressed in Jy beam⁻¹.
