I've been looking out for these, and have seen 1 copy out of 200 regular ones. What is the value of this thing if any? And...just how rare is it? Less rare than the Mamas & Papas "toilet" cover? I've certainly seen 10 times the number of butcher covers... (O, I should say)- the "beard" cover has a pic of the lads with 3-day stubble, on the REAR cover, later deleted.
