I will put the 'answer' here in a couple of days - it has to do with the greyish blob in the centre in the mortar. Once you see it you will never see the plain brick wall again.

This is amazing. Once you find it you will always see it. Have now put the answer in the other photo for all those getting frustrated
Both photos appear identical to me - I've tried the one-eye trick, blinking rapidly, focusing just to the sides to see if my peripheral vision can spot it ... no luck. Please put me out of my misery

there is a cigar sticking out of the wall. Grey blob is the end, the rest is the mortar to the right of it. I have darkened it and lightened the wall in the attached photo.
