The sleeve mentions ‘The International studio orchestra’. It is a generic term referring to the different orchestras that Pierre Arvay conducted for recording his compositions.
Depending on the pressings, darker or lighter green on the sleeve.
Other possible variations over the course of the pressings: different round record labels (red or white-blue-red), various sleeve printing types (for example ‘glossy’ appearance or not), different sleeve printing companies, different contact details for the Music De Wolfe office in London, pressing of the records in England or Holland.
