Pehr Gustav Bylander was active in Gothenburg from 1804 to 1859 and was one of Sweden's most well known and successful mirror manufacturers. He supplied mirrors with console tables to many great houses in Southern and Western Sweden, including Skottorp, Sperlingsholm and Stjernsund. The Nordislea Museum in Stockholm has several examples of his work.
Similar examples of Bylander's work are illustrated in Neoclassicism in the North, Swedish Furniture and Interiors 1770-1850 p.162,(ill.168), p.207 (ill.9) and specifically p. 175, where a pair of mirrors with similar eagles and carved columns can be seen illustrated in Skottorp. Skottorp was built for the Royal Secretary Frans МРrnestedt, it was bought by his descendant, the Commercial Councillor Peter Möller in 1813.
