70 - 80 yr old Plastic Sign Indian-head 2nd Division Korea Infantry shop

Product Name: 70 - 80 yr old Plastic Sign Indian-head 2nd Division Korea Infantry shop
Up for sale is a plastic sign that I honestly know little about. It is plastic which makes it impressive that it has stood the test of time to this point. The graphics and the lettering are all raised and the colors are still very vivid. And it looks to be hand painted as well . The plastic is brittle as you would expect for it being so old. It'll be shipped in a frame just solely for protection. ** Update: This is a sign for Korea 2nd Division infantry. Possibly a one-off custom sign from korean war. Thank you and shout out to Mr. Dust_Dive_TX for the info! I've been to an enormous amount of auctions, yard sales, antique stores, Etc. This is the first one of these I've ever seen. Anybody could give any more info about this it would be shop appreciated.
