A Mellotron M400 in clear lucite

The Mellotron is an electro-mechanical, polyphonic keyboard originally developed and built in Birmingham, England in the early 1960s. The heart of the instrument is a bank of parallel linear magnetic audio tapes, which have approximately eight seconds of playing time each. Playback heads underneath each key enable the playing of pre-recorded sounds. (Info via Wikipedia)

The Mellotron was used by British rock artists Graham Bond and Mike Pinder before it was used and brought to public popularity by The Beatles in the song “Strawberry Fields Forever”
