This is an advertising postcard for Polzela Nogavice (Slovenian for “socks”, according to Google) of Polzela, Slovenia, sent to me a couple of months ago by Žiga, whom I met in the Postcrossing forums. Judging from this card and from their website, socks and stockings seem to be synonymous; perhaps the better translation for nogavice is “hosiery”. If you need some, it looks like Polzela can accommodate you, even if you have legs up to here.
The stamps apparently show an extremely rare species of chickweed. I’m thinking of exporting some of the more common chickweeds to Slovenia from my front lawn.
