designed by Rune Söderqvist, who designed most of ABBA's record sleeves. The ambigram first appeared on the French compilation album, Golden Double Album, released in May 1976 by Disques Vogue, and would henceforth be used for all official releases. The idea for the official logo was made by the German photographer on a velvet jumpsuit photo shoot for the teenage magazine Bravo. In the photo, the ABBA members held giant initial letters of their names. After the pictures were made, Heilemann found out that Benny Andersson reversed his letter "B;" this prompted discussions about the mirrored "B," and the members of ABBA agreed on the mirrored letter. From 1976 onward, the first "B" in the logo version of the name was "mirror-image" reversed on the band's promotional material, thus becoming the group's registered trademark. Following their acquisition of the group's catalogue, PolyGram began using variations of the ABBA logo, employing a different font. In 1992, Polygram added a crown emblem to it for the first release of the ABBA Gold: Greatest Hits compilation. After Universal Music purchased PolyGram (and, thus, ABBA's label Polar Music International), control of the group's catalogue returned to Stockholm. Since then, the original logo has been reinstated on all official products. 1973–1976: Breakthrough Eurovision Song Contest 1974 As the group entered the Melodifestivalen with "Ring Ring" but failed to qualify as the 1973 Swedish entry, Stig Anderson immediately started planning for the 1974 contest. Ulvaeus, Andersson and Stig Anderson believed in the possibilities of using the Eurovision Song Contest as a way to make the music business aware of them as songwriters, as well as the band itself. In late 1973, they were invited by Swedish television to contribute a song for the Melodifestivalen 1974 and from a number of new songs, the upbeat song "Waterloo" was chosen; the group were now inspired by the growing glam rock scene in England. ABBA won their nation's hearts on Swedish television on 9 February 1974, and with this third attempt were far more experienced and better prepared for the Eurovision Song Contest. Winning the 1974 Eurovision Song Contest on 6 April 1974 (and singing "Waterloo" in English instead of their native tongue) gave ABBA the chance to tour Europe and perform on major television shows; thus the band saw the "Waterloo" single chart in many European countries. Following their success at the Eurovision Song Contest, ABBA spent an
