According to a contributor on Discogs, the Philips Hi-Q equipment was launched in 1955 and this record could be from the same year. I tend to think it’s from 1956, because of the text “All Philips records are hi fidelity records!” on the back cover. The record wasn’t commercially available but was used for various demonstration purposes. I guess it was sent to shop owners and used on hi-fi meetings.
