This is from an early printing, red-brown on blued paper, plate 32. 'BH' does NOT have the later constant flaw "gash on forehead".
Is this block is of interest to a specialised Penny Red collector who has the later printing(s), with the Flaw? The price is £20.

Hi lkfman -- "Postal Markings" isn't the obvious forum for this. I can move it to the sales forum if you like?

Hi
That would help me a lot please, as I am still finding my way. I did set out in Sales forum I think but obviously took a wrong turning.
Thank you.
PS I don't use Internet explorer so had difficulty adding the image. Picture wizard works ok for me normally but I think I was lucky that my image got there anyway.
Regards.

Done. It should hopefully work with any browser (although different browsers may use different terms for things, unfortunately).

Sold - as much for the nice block and the Welsh postmark, rather than the absence of the later variety.
