Lot of 2 LARGE Art Deco Mid Century Silver and similar items

I've tried to take pictures of any markings on these items, the butterfly is more gold toned and there's definitely a marker with metal purity/year/makers mark but I can't tell what it is, hence I've included 2 pictures. The bowtie is pure silver color with the number "25771" on the back. I've included a picture next to a Morgan dollar for size and the weight in grams for each item. (The Morgan isn't included sorry to say!). These are beautifully intricate designs. If I were a woman and lived 80 years ago, I'd definitely wear these (haha). But I know there are collectors out there and who knows, they may be from a famous designer that I wasn't able to find through my good friend Google. This sale is for both items! Can't take returns as I've documented and took pictures of as much as I could! Make sure to ask any further questions before purchase knowing this. Happy bidding.
