Audio-Visual Direct Lightweight Aluminum Flip-Chart Presentation Easel, 177 cm (Black, Pad Holder)

Will this help me get promoted?

I have a poster that measures 24 by 36 inches will this work for that picture? It is not heavy, just big.

Will this hold a paper poster? It's not clear how it attaches to the top and whether a single piece of paper could be secured.

Will this hold the Post It flip chart that can also be hung on a wall?
