J9ABO 1948 Okinawa, Ryukyus Islands

I am sure that this card was used by the operator to confirm his contact when operating as KR6AB.
He (Arthur M. Burton) was the op of both stations. Notice "KR6AB" typed in the upper left-hand corner of the card.
I have found no other amateur radio activity by him.
