Romare Bearden Silkscreen

I’m pretty sure it is not offset print but no visible numbering and signature. I always wonder why a framer would cover such writings with the mats but I hope they did not do their job right this time. I’ll take it out of the frame and hopefully the mats are not glued hard.

 

Here is how the signed copy should look like.

Did you take it out of the frame? And if you did, what did you find?

 

Sorry I forgot to update. Bad news, a 1980 poster.

 

Oh, sorry!
