I think this is a piece from Siddy's Ecuador series.
Paperweights by individual makers are somewhat undervalued, in my view.
Particularly if you compare the number made in an artist's lifetime with say, the number of paperweights produced by a factory in a year!
Depending on what you paid for the job lot, and whatever else was in it, if you ask double what you paid for the whole lot, for Siddy's paperweight, both you and the buyer will probably be doing ok!
