This may be a bit of a stretch, but humor me and use a little imagination.
These may be related to Kingman Army Airfield.
Their official mascot (approved by Warner Bros.) was Bugs Bunny. The boxes below the bunny may be hangers and barracks.
The two interesecting line represent the runways and the little crosses represent aircraft parked in the field.
To me, there is more than a little irony that the crosses mark the "final resting place" for these planes.
Following the end of WWII, thousands of war surplus aircraft were flown to Kingman where they were systematically
destroyed by a huge hunk of steel suspended from a crane hook - a guillotine of sorts. That's what they called it back then, anyway.
They were then melted down and the aluminium was recycled.
Perhaps these cufflinks belonged to a worker at Kingman.
If so, it would date them to the late 1940's.
