Kalle på äventyr

Kalle på äventyr is a Swedish comic series launched in 1946 by B.M:s bokförlag, a publication that has continued to the present day despite comprising only a single issue. It stands as a unique, long-running oddity in comics history—a series defined by its enduring presence rather than a prolific output, and it matters as a testament to the quiet persistence of niche publishing in Sweden.
