Life Magazine published an international edition.  The Dec. 16, 1963, issues was focused on the death of President John F. Kennedy and the new president, Lyndon B. Johnson. Life International was different from the U.S. edition.  According Magazines by Joseph website:

Life Magazine International Edition : These issues were distributed in various countries other than the US, typically in the UK, Europe and Asia. Each biweekly issue contains selected content of international interest from the previous two “regular” Life Magazine issues. There is very little advertising content, so these issues tend to be thinner. The cover may be one of the previously published “regular” Life covers or another photo relating to the international stories featured in the issue. The International Editions began in July 1946 and ran as late as 1969. International Editions are much less common than the regular editions.

This edition seems to capture the preceding two weeks of history.
