The issue date of this 75 card version does not seem to appear anywhere, so does anyone out there have any ideas? Secondly this set is stated to be cards 1-50 of the standard version plus 25 extra cards.As far as a list I had a breakthrough, as there is a list online, with card pictures - check the av8r blog / Wills Aviation.
The connection with Blackpool concerns a ride in the pleasure gardens called Sir Hiram Maxim`s Captive Flying Machine - which is thought to be the oldest in Europe. It was immensely successful, but he was never satisfied with it.
If you look at postcards of the 1904 Earls Court Exhibition you will spot one there, either in the distance or fully featured; one of the best of them is a really close up view captioned "Fly by Night".
The survival of the one at Blackpool proves this entirely wrong.
