Stockholm (Sweden)

The man in the Stockholm arms should be St. Erik (patron saint of Sweden) but when the city wanted to standardize the arms in the 1930's, the artist used a statue in an old church as a model, a statue that later on has been identified as St. Olof (patron saint of Norway - though very appreciated in Sweden too in the catholic era).
Elias Granqvist, 3 October 2000

The flag is a banner of the arms; arms dating from 1376, formally granted on 19 January 1934.

The Arms of the city were officially granted on January 19, 1934 by the King. Notice that this version is the image of St. Erik in black outline and yellow background, over a blue background. The modern coat of arms (above) (which is also a flag variant according to page 163 of the "Grafisk manual för typografi Stockholms stad. version 2.0. 2009") is explained in detail as the revised logo and its modifications.

Very rarely this version (colored coat of arms with black font type is used), mostly for ceremonial purposes on official communications.

The background use of St. Erik dated back to the XIVth century, more specifically in 1376 on the city "sigill" (English: Seal), although it was not until 1923 that the "stadsfullmäktige" (English: city council) formally adopted St. Erik as the city symbol, confirmed by the King in 1934. Artist Yngve Berg was commisioned in 1923 to design an image to be used in the city as standard version (because there were several graphic interpretations different from one another at the time). As proposed by Ivar Simonsson (archivist) it was based on the image of the statue on Roslags-Bro kyrka (English: Roslags-Bro church), and thus, it was the modern version (above) of St. Erik. However, as approved on January 19, 1934, and registered in the Patent- och registreringsverket (English: Patents and Register Offce) in 1974. The current version (above) used was designed in 1961 by Karl-Erik Forsberg (source: http://www.stockholm.se/OmStockholm/Fakta-och-kartor/Stadens-historia/St-Erik/, currently unavailable, accessible only through here: https://web.archive.org/web/*/http://www.stockholm.se/OmStockholm/Fakta-och-kartor/Stadens-historia/St-Erik/, and https://sv.wikipedia.org/wiki/Stockholms_stadsvapen), adopted as the city symbol in 1997, the latter wrongly labeled as a "variant", but it is rather a logo, as the Brand Manual states here: https://varumarkesmanual.stockholm.se/grafisk-profil/logotyp/ (an earlier manual can be seen here:
http://www.stockholm.se/Global/Om%20Stockholms%20stad/Grafisk%20manual%20och%20logotypen%20st%20erik/grafisk_manual_v1_2006_low.pdf).
