SAFETY WEAR FOR AERONAUTS

Flickers! Flickers! Flickers!

=High Level Flickers=

"_He that is down need fear no fall_"

_Fear not! You will fall lightly as down!_

Hansen's air-kits are down in all respects. Tremendous reductions in prices previous to winter stocking. Pure para kit with cellulose seat and shoulder-pads, weighted to balance. Unequalled for all drop-work.

Our trebly resilient heavy kit is the _ne plus ultra_ of comfort and safety.

Gas-buoyed, waterproof, hail-proof, non-conducting Flickers with pipe and nozzle fitting all types of generator. Graduated tap on left hip.

=Hansen's Flickers Lead the Aerial Flight= =197 Oxford Street=

The new weighted Flicker with tweed or cheviot surface cannot be distinguished from the ordinary suit till inflated.

Flickers! Flickers! Flickers!
