Note 13: At VEPRO, Roepstorff worked with several of the cartoonists who a few years later became animators on the feature film "Fyrtøjet". Among these were Børge Hamberg, Bjørn Frank Jensen, Kjeld Simonsen (Simon), and Erik Christensen (Chris). Bjørn Frank Jensen can tell the following about this: “[…] Around this time [1938] I met [crossed out: for the first time] Børge Ring. Jørgen Müller had also returned home from London and worked at Gutenberghus, and Ring, who was in Copenhagen to attend the School of Arts and Crafts, worked for Müller in the afternoon, after school. Ring picked me up at Monterossi and we have been friends ever since.

Ring, who had another great talent next to drawing, switched to music, and I applied to Gutenberghus, to be an assistant to Jørgen Müller, on various short commercials, among others. a film for Steffensen's Sausages with the Nordic gods ["Pig of the Gods"]. In this movie, I was even allowed to animate a small scene.

Müller left Gutenberghus to set up a new company with Mik: "VEPRO" in Hovedvagtsgade, and Gutenberghus hired Nils Skjoldborg to lead the film department, and I had a fun time with him. He was a very practical man, and made both live action and cartoons.

When VEPRO moved from Hovedvagtsgade to Hellerup, I moved in and worked with Kjeld Simonsen, Børge Hamberg, Erik Christensen and Müller's old assistant from London, Roepstorff, who was head of the intermediate drawing department. He was considerably older than the rest of us, and more driven in the subject, but without ambitions to animate. Every now and then we heard rumors about a man named Erik Rus who was working on a cartoon with a character he had created called "Peter Pep". There was also another person who tried to assert himself, a former assistant of Jørgen Müller: Richard Møller, who had an idea to make a cartoon about "Fyrtøjet". I remember Ring and I sought him out to talk to him about the project. He had a very short piece of film with the soldier marching on a "pan" [panning background]. The most striking thing about the scene was that the soldier got smaller and smaller the further he marched. Ring and I were already thinking about working together at the time, but nothing came of it when Ring went back to Funen to take the matriculation exam. […] ”

If one is to believe Bjørn Frank, it seems that Erik Rus has not worked at VEPRO, and one would also think that if that had been the case, Bjørn Frank would have had to know about it. However, I have not been able to get this confirmed or denied, as Erik Rus died (in 1988) before I had time to interview him, who incidentally suffered from advanced muscle wasting. And Børge Hamberg died already in 1970, so it has not been possible to ask him, nor others who worked at VEPRO at the time, as most are either anonymous today or may have long since passed away.

Among VEPRO's staff were also several younger ladies, who later became inkers and colorists on "Fyrtøjet", e.g. Henny Hynne, Esther Andersen, Karen Bech, Grethe Wrangel, Jenny Holmqvist and Else Emmertsen. The latter two became, for the former, head of the inking and coloring department at Dansk Farve- og Tegnefilm A/S from around the beginning of 1943 to 1944, while the latter took over her position in 1944, when the inking and coloring department had been moved to premises, first on Strandboulevarden in Østerbro, later in Stengade in Nørrebro, and finally on Vesterbrogade in Vesterbro.
