Teniers started his career painting hundreds of copies after old masters. However many forgers produced paintings similar to those he painted.
During Teniers' lifetime many artists were used to copying his works simply in order to improve their own styles.
Teniers also lent his hand to the works of many of his pupils or colleagues and had himself many followers such as Mattheus van Helmont, Egbert van Hemskeerk, Hendrik Govaerts, B. van den Bossche, Jan Joseph Horemans, H.M Rokes called Sorgh, Theobald Michau, Beschey, Pieter Angelis, Apschoven, David Ryckaert,
M. van Kessel, W. Dietrich, A. van Maas, Pieter van Laar and even P. Wouverman.
Bamboccio had many Flemish or Italian imitators such as Jan Miel, Jan van Ossenbeck, Thomas Wyck, M. A Cerquozzi, Philips and Pieter Wouverman while the latter reportedly burned several drawings and copies after Bamboccio on the eve of his death.
Meanwhile, many tapestries were produced with scenes after Teniers without the artist's consent.
Teniers apparently was amused, notwithstanding the fact that several copyists or manufacturers producing tapestries were promoting his name. He even was said to have gone as far as spreading the rumour of his death and scores of collectors and dealers reportedly rushed to his house to acquire his works at solid prices before Teniers reappeared as if he had resuscitated.
Frans Hals had also many imitators among his pupils and followers and Adriaen Brouwer painted several works that Hals sold with his own signature. Brouwer was then copied by Joos van Craesbeck and also by Teniers or Saftleven.
Dirk Hals found an imitator in Jacob Duck but also copied his brother Frans whose other followers were Salomon de Bray and Jan de Bray.
Adriaen Van Ostade was much inspired by Brouwer and was copied by his brother Isaac as well as by Jan Steen, Cornelis Dusart, Cornelis Bega or van Hoogstraten.
