Rolf lived in Paris for a few years, establishing connections with artists and gallery owners. Among the artists, he got to know Bengt Lindström, already established in Paris, whom Rolf exhibited at Galleri Glemminge in 1974. Another important connection was Galerie Ariel in Paris, through which Galleri Glemminge could introduce artists like André Marfaing, Arthur Luiz Piza, Roberto Matta, Man Ray, and Karel Appel.

Over the years, the gallery became a crucial center for international art. In 1977, Beate Sydhoff, then-secretary of the Royal Academy of Fine Arts, praised the gallery and emphasized its position in "world art." The gallery had previously held a major exhibition with the Dutch artist Karel Appel. Birgitta Westberg-Dahlström, Rolf's wife, who had been running the gallery with him since 1974, highlighted the significance of the exhibition. Rolf, she said, would listen during the nights and rush barefoot in his robe to the gallery at the slightest sound to ensure everything was in order. Other international artists exhibited included Salvador Dali, Picasso, Alberto Giacometti, Matta, Man Ray, and Palle Nielsen.

Rolf was driven by a strong passion for art and artists. Birgitta recounted how he selected the art he wanted to sell. He would often visit the artist, sit in front of the works, and take home the ones he was interested in, continuing to contemplate until he made his decisions.

After 32 years of working with the gallery, Rolf passed away in 1999. In response to his passing, HC Ericson, a professor of graphics, wrote the following in Ystads Allehanda: "The gallery became a gathering place, a cultural watering hole, not only for visual artists but also for writers, actors, and musicians. He had a high-quality tailoring and was a word and image person, thus also an educator. Rolf was outstanding. I miss his work and the art scene that the gallery represented.
