- Shown first above is the very first issue of this album with blue labels and gold lettering, and the speed designation unboxed (both on the cover and the labels). It was probably released late 1951 or early 1952. The second series of images shows a (prob.) 1953 reissue with a yellow cover and boxed speed designations on both the cover and the labels. The third series of images shows a 1956 or later reissue, with a new cover.
- An ad for this album can be found here (“De Radiogids”, Sept. 7, 1952). Note that the ad shows the Philips Minigroove logo with the speed designation boxed. This means that the unboxed logo was used for a limited time only and it was probably replaced in 1952.
