Vintage Murano art glass Seguso? duck pair with copper infusion.

The pair features very high quality and detailed glass. I think they are a male and female so sold as a pair only. The ducks have a myriad of colors: pink/red, green heads, white ish opalescent bills and eyes. Blue near end of neck, white on main bodies to clear glass in wings. Wavy bands of green, reddish, blue shades, sometimes muted leading to their tail end. The copper has intermittent vertical like striping stretched bands in head and oval shapes near end of neck color into body. Oval pattern in back plumage with different bands of color into tail where copper ovals break apart into streaking lines. Very heavy. I think they are older due to wear scratches on underside of base. They are not marked but may be Suguso. Good condition with no fractures. Underneath, wear/scratches on bases due to age and use. The left is the female; she has a few small circular patch scratches near bottom of chest. No chips on her. Some other light surface wear but minimal. The male has some wear scratches on bottom as stated. He has a few small miniscule flea bites near bottom of underside with a few nicks. On his bottom, there are some black spots under the glass; made that way. Both sold as is and as found. He has other minimal scratches but are minimal. Both will have to be shipped separately in flat rate boxes due to weight and delicacy of them. Female is 8.25" X 6.5" X 3.75". Male measures 6.25" X 6.5" X3.75".
