When most people think of Pop art, the big names come to mind: Andy Warhol, Roy Lichtenstein, and Jasper Johns. The Walker Art Center in Minneapolis reminded the art world that the genre is actually a much larger phenomenon with its critically-acclaimed 2015 exhibition, “International Pop.” As the show travels to the Philadelphia Museum of Art, opening on February 24, here are 10 under-appreciated masters of the field whose work you can see in the show.

And for more Pop art on offer, check out artnet Auctions’s Pop art sale, which runs through February 24.

1. Antônio Henrique Amaral (1935–2015)
Pop goes political in this piece by Antônio Henrique Amaral, who was an outspoken critic of the military dictatorship in his native Brazil in the 1960s, as well as US involvement in Latin America. He maintained an appreciation for the absurd up until his death at 79, last year.

3. Rosalyn Drexler (1926–)
This Rosalyn Drexler work, with its subject matter and dramatic contrast, recalls Robert Longo‘s classic “Men in the Cities” photographs of men in suits, but was painted by the American artist over a decade earlier.

4. Erró (1932–)
This eye-catching commentary on consumerism by Icelandic artist Erró is almost good enough to eat. “I paint because painting is a private Utopia,” he once wrote. (To catch the artist’s work in New York, check out “Erró: Paintings from 1959 to 2016,” March 1–April 23, 2016, at Galerie Perrotin.)

With this Mona Lisa-inspired work, Jirí Kolář, a Czech poet, writer, and painter, embraced Pop art’s appropriation of the zeitgeist in its various forms.

7. Kojima Nobuaki (1935–)
Jasper Johns himself once posed with a group of these ominous American flag-clad figures during a two month artist’s residency in Kojima Nobuaki’s native Japan. An untitled flag work featuring a similarly draped figure is in the Museum of Modern Art’s permanent collection. Nojuaki grapples with themes involving US power and individualism, throughout his decades-long career.

8. Dalila Puzzovio (1945–)
Born in Argentina, Dalila Puzzovio was also a fashion designer, as evidenced by this stylish—and prizewinning—footwear. The Buenos Aires native created the iconic “Dalila doble plataforma” (Dalilia Double Platform), which she frequently invoked in her artwork.

9. Yokoo Tadanori (1936–)
As a well-known artist and graphic designer in Japan, Yokoo Tadanori was inspired by traditional Japanese motifs, as well as psychedelia—influences that are easy to spot in this trippy painting above, which references the Imperial Palace in Tokyo.

10. Jana Želibská (1941–)
Slovakian artist Jana Želibská told the Tate Museum in 2015 that she was not a Pop artist, but admitted that “I have used some expressive means of pop art in my work.” She arrived in Paris during the 1968 student revolutions, and was steeped in nouveau réalisme as well as Pop.
