A few days ago we had an event in Universidad José Antonio Paez in my city, the organizers required a banner, I did it and sent to lithography to print. I leaving here the invoice.

I'm asking for partial funding. Because I understand that this is not normal price for it in another countries. So the half will be fine for me
