Who designed the Queen crest used on the cover of A Night at the Opera?

Freddie Mercury designed the Queen crest used on the cover of A Night at the Opera.

Mercury created the emblem by combining the zodiac signs of all four Queen members with a large letter Q and a crown. The two Leos represent Roger Taylor and John Deacon, while Brian May was a Cancer and Mercury was a Virgo. The crest also includes stylized fairies associated with Mercury's own sign.

The design appeared prominently on A Night at the Opera, released in 1975, and became one of the band's most recognizable visual symbols. Its ornate style reflected Mercury's interest in heraldry, theatrical presentation, and visual detail.

The crest is sometimes incorrectly attributed to a professional graphic designer or to Brian May because of its connection with the whole band. However, the concept and design are credited to Mercury, who had studied art and graphic design at Ealing Art College.
