please, help me

Hello everyone, I need your help. Can you tell me how to say in English the object in the picture?
This is the one in better condition, but I've found three more (the works, kind of magic and the miracle) in the garage where I lived before. I haven't found a treasure, them was given to me by a record store at their times but I forgot to have them. are not in great condition, but I thought I put them in place and perhaps sell them, but if I do not know how to define them is very hard...
I thank you all, best regards

I would say record advertising merchandise or similar

Do they have "fold-out" portions on the back that allow them to stand up? If so, they are called "Standees".

Can we have a look at the other 3 please?

This just looks like basic promo material to have in record shops.

thank you all for the help.
the posters are (was) placed on the floor. unfortunately, however, three of the four pieces were heavily damaged by moisture. This is what remains of The Miracle (the others are worse).

I'll take the bottles though.

"Poster flat" if it is 12 inches by 12 inches! Especially if it is on a cardboard like material!
