Finding Tin Robot shops in France and Spain

[Mosser]

HI everyone,

I'm planning to take a trip to Barcelona, Spain as well as Paris, France during the Christmas holidays,

is there a market or shop for vintage tin toy robots there? Or a museum? Neighbouring cities are good too!

These shops might be hard to find on google maps,

So I'd like to ask if any of you ‘museum curators’ know anything more about it.

Thanks！
