Vintage Czechoslovakian kitsch ash tray in shape deals of Sparta cigarette packet

Vintage ceramic ashtray from deals Czech Republic. Delightfully kitsch and well-made - in the shape of a packet of traditional Sparta brand cigarettes. Made in Prague (Praha) during the Communist period in the 1970s. No chips or cracks but on close inspection you can see some crazing. I've seen ashtrays of this shape before but never this brand, so it's quite unique.
