It would take me right back to Christmas 1988, unboxing the Batman pack, and being disappointed that my father hadn't purchased the Spectrum 128 that I had recommended! 
...partly because the modulator included was faulty, requiring the family to wait until boxing day (or was it the day after?) before going into the city to organise a replacement from the store.
This is how I felt when Mum came back with an A500 instead of the C64 I asked for. And the machine had to be returned
because of a faulty PSU too. Uncanny.
But my A500 did not come with this disk, all that info was in the manual. I would like to see this disk. I have seen similar on the Mac Classic.
