It's a while since we had any major PSB errors, but Matthew has sent this picture of his book which has only one of the Miniature Sheet panes, the left-pane being omitted.
I'm assured that it is not a case of the missing pane breaking along the heavy roulettes - it really is missing. So, sold short by Tallents House, but I advised him its a keeper for now. Anybody interested in this please let me know and I'll pass on your details.
