Best-looking adult Common Gull on the planet?

This gull was a smasher - the most striking Common Gull I have seen this winter and maybe the best-looker out there? I had been looking out for this unusual wing-tip variation of adult Common Gull (as illustration No.3 on page 32 of Olsen & Larsson). With the extensive mirrors on primaries 10 and 9, very long grey tongue on primary 8 reaching as far as the mirror of P9, and chequerboard like effect on the underwing of P6-8 this bird certainly stood out in flight as it wheeled around Nimmo's Pier in Galway on 28 December.
