Vintage Specimen Display offers Curiosity Large Insect Beetle Moth

When offers I spotted this at an estate in Connecticut, I had to grab it. These are amazing specimens. They are very large insects. I wish I knew the names of each one. Maybe you do?
Would look great displayed where it can be appreciated.
Glass on both sides. Wood frame looks handmade specifically for this display.
Because of how reflective the surface is, it is tough to get perfect pictures.
Measures not quite 12.5” x 7.5”
