No would not be !! These were stamped at the factory with the impressed mark !! It was made in the mold or stamped as greenware while the clay was soft !! Hull,, Hall and others were made here and usually have “Made in USA” or just USA on them !! They never used Japan made items !!
Many like the roosters for decoration !! Best is to check ebay and see what similar size ect are selling for !! My guess is around $20. for the pair !!

marthahill I have an idea could it be like from hall. hull, royal Copley companys like those back then. some times they didn’t mark all there items. just wondering

eeiram1 these are very neat looking I have never seen one like these… keep them treasured… there beautiful.

The are figurines although the base is cupped like. They are about 8 inches tall at the tail feather. Thanks

Just wondering does the roosters head come off like a container for something or are they just figurines ?? If so how big are they ??

Thank you for the help with this. Been wondering about this for a long time.
Do you know how old these are and if they are worth anything
