Set of gold male and female birds

Obtained from an Estate sale. Obtained quite a bit of china and pottery. Want to know if this has any value. Can’t find anything on this specific piece. I have two identical mugs.

A.G Brooks Slave Trading House 1858 is what the key and medallion read. Very good condition.

Glass shades with brown leaf vines decorating it. I have two of them

Hi! Someone is offering me this French Gobelin; he says it's a Dubon brand from France and made during the second half of the XX century.
The frame is made of wood, gold leaf, and plaster. No glass. It measures 200 cm height, 90 cm tall.

My questions are:

Does anyone know more about this brand?
Do you all think that antique was made during the second half of the XX century?
How much does it value?

I am trying to get all this info before buying it to ensure I am making a good choice and not overpaying it.

Thanks!

Crystal vade. Pretty heavy, no makers marks on it that I can find! Alternating pattern around it. Star shape on bottom
