1915 Bronze/Brass S. Morani Nude Lady w/Swan Book-ends

I found these at a thrift store today. I looked up S. Morani book ends & found a lot of them by this artist but not this pair. Can someone tell me what these are called so I can see what they are worth/what I can sell them for? (I got them for $9.95!)
PS - Are these really from 1915? the bottom is solid & not hollow like a lot of other ones I've found before - that's a good thing, right?
Thanks!

The copyright is that old, but not sure this pair of bookends is.

Original maker was National Metalizing Co. of Garwood, NJ.

 

leda and the swan - how'd you do that?!

 

Think these could be bronze clad. The base is moulded plaster(I think I can see some white chips) then sealed with wax then electroform bronze plated. Here’s another pair on Etsy described as bronze clad.

It's one of the classic tales in Greek mythology, and a very popular art motif.

 

Edith Hamilton. Didn't everyone read this as a child?

What an interesting article. Must have been a bit pricey in their day. Think they looked newer to me because I was comparing to how I think they would look as cast bronze. Journey has a very nice find, she says covetously.

 

It is interesting. I must confess even as a sculptor who has had items cast in hot metal bronze and cast items in bronze resin myself that I had never heard of bronze clad casting before.

 

I put them on eBay for $295 & accepted an offer for $225!
(turns out they were bought by another eBayer who sells high end (expensive!) antiques - including some book ends).
In my description I said I couldn't find another pair anywhere & it was probably because having nude book ends in those days was very risque so not many people bought them - and you can't find them today because those who were lucky enough to find a set do not want to sell them!
Waiting to see how much they are resold for! But I'm happy - everybody has to make $ and hopefully I have a new customer for some of the old & unusual stuff I like to find!
Thank you all for your help in identifying Leda & the Swan (Blooey!)
