Hell's Kitchen Flea Market dealer, "March Hare,"
asks, “Where would clowns and the Marx Brothers be without seltzer
bottles?” March Hare's got one. And not just any one, of course, but a seltzer bottle from Czechoslovakia, 1950s or '60s. It’s in mint condition. So, yes, it still makes that great pshhhhh! sound when you spray water out of it.
Apparently,
there was more slapstick comedy or cocktail mixology going on behind
the Iron Curtain than the CIA could ever have guessed! ;)
