wooden 6x8 Folding Picture Frame decade request 25

I have a wooden 6x8 Folding Picture Frame.I would like to request the decades
that this was made for insurance claim purposes because my hot water
tank burst and they got thrown out in mitigation. However, my insurance
wants me to date everything that got lost in water damage. Mitigation took
this picture. Thank you for assistance in this request. Regards, Rob
