Interesting. I hadn't heard about the Alexandra Palace event later this year.
Re the Telefis Eireann test card E, that same card was used in the U.K. (with different station ident, of course). I don't know how long "E" was employed in Ireland, but it's interesting to note that it was not well received here and was soon abandoned, with the former test card D continuing in use until fully replaced by the color card F.
Many more images of these cards can be seen here:
