I have a pair of blue glass decanters with white enamelled figures of a boy and girl on swings?

They are a pair and the boy is on one decanter and the girl on the other …they look victorian …the glass is dark blue and the enamelling is white they are about 12-14 inches tall and have handles on the sides they have been in our family for over 60 years.
The stoppers, may be missing, if there were any origionally
