Navy blue with white vinyl trim canvas travel bag has one outside pocket and a metal zipper. The British Overseas Airway Corporation ceased operation in 1974, so this bag would date to the late 1960's, early '70's. Made in England. It measures 16 1/2" x 9" x 5 1/2".
The only condition issue is the A on the side without the pocket has some wear, otherwise the bag is in excellent condition.
