Hello my name is***** am a certified appraiser and would be happy to help you. Can you post a photo of the flag for review. This will help on seeing the item and being able to give you an accurate evaluation. I see there are two flags one 46 x 64 and another 46 x 62
ok I am always happy to help so just let me know. These large ship flags do hold a great deal of value and when storing them place a dryer sheet "bounce" in with them to prevent moth or beetle damage. This will protect them as the moths or bugs repel from the smell given off.
