Ashtray (15) - Ceramic - Curious advertising ashtrays

Lot of fifteen peculiar ashtrays, ceramic, various countries, second half of the 20th century.

Partly these are advertising ashtrays, partly just oddly shaped specimens.
In any case unique pieces that you won't come across very often elsewhere.
Especially now that smoking is being discouraged everywhere, ashtrays are the new collecting trend.
Dimensions are hard to specify; as an indication: the red typewriter is 13 x 13 cm.
All specimens are intact and as good as unused.
Only the ashtray of the flight attendant with a joint shows clear signs of use!
