Our card today shows an actual fireball, but looking for such things is also a good way to hone in on the Perseids, as the larger ones do indeed have glowing heads, though they move in a more diagonal manner than the fireball shown here.
The fireball on this card was seen in 1965, and it "streaked through the April sky from below Washington to Ottawa, its sinuous trail glittering in the twilight". You can read more about it in an excellent article which has been uploaded by Harvard University.
This set does not appear in our original British Trade Index part two, instead it waits until part three, issued in 1986, where it is recorded under section 3 of the Brooke Bond listing, for "North American Issues", between 1959 and 1974. The entry reads :
- Series 12. The Space Age. Nd. (48). Issued 1969 ... BRM-17
Unfortunately these were not recorded in our updated British Trade Index.
