When I purchased these, I was told they were models of shoes used by shoe salesmen in the 1940s or 1950s.  I have seen some similar but not identical ones which are listed as toys.  In any case, they are thin, hard plastic and were manufactured in Hong Kong.  These could use a light cleaning and are not perfect - the laces are a little wonky, and there are a couple of tiny chips along the edge as shown in photos 5 and 6.  The detail on these is fantastic.   I try to share as much as I know about items, and I am certainly happy to answer any questions you may have before purchasing.  Thank you !
