Vintage Japanese Growth of the Cultured Pearl Framed Display

Description

Vintage Japanese Growth of the Cultured Pearl framed display. Approximately 12 3/4" long, 10 1/2" wide, and 1 1/8" thick. My grandma used to own this and I inherited it, so I'm selling it for someone who can make use of it.
Some of the shells have cracked and there are a few loose shell fragments in the display. There is some paint on the glass from the frame being painted. There are obvious signs of aging and use. The back panel is warping. See pictures for details.
Display comes from a smoke-free, pet-free, clean house.
I have the shipping method set for USPS Parcel Select Ground since that is the cheapest, however this shipping method is a bit slower so if you would like a quicker (more expensive) method, please let me know before purchasing the item.
Thank you for looking and please let me know if you have any questions! Also feel free to send me any offers you have. I am selling some other figurines, vases, plates, and beads so check those out if interested (I combine shipping)!
