look at it this way:
if you want an authentic picasso his total output would be around 900-1100 pieces from which you choose.
if you want a 1st batman well there is about 50-100 tec27 copies known to exist.
which one is scarcer?
So it's Any Picasso vs Tec 27? That doesn't make sense. How about any Picasso vs any batman? Which hold more vale
Bad comparison, if someone wants a specific issue of batman (I.E. Tec 27) than put that , vs any One specific Picasso , (and if that's the case, it's not even close in terms of value ,favor for Picasso)
