I think Ron may be right. Hippeastrums generally don't have upward facing flowers, but that point may have been lost on the makers of fakes.
Yes, they mean a plastic plant. No I don't think it is. Center, straight upright leaf blade, just to the left of tall center flower stalk, is faded to yellow on upper half. Far right leaf tip is bent upward where it is growing into the glass. Leaf just to the left of that has shriveled brown end. It reminds me a little of this Hippeastrum 'Benfica', although not exactly the same. Some Hippeastrum cultivars do have upward-facing flowers in good conditions, such as this 'Double Dragon, and this one.
Hi, Many tks for all your kind answers, I can assure everybody that this is a natural plant I just want to buy one that is why I wanted to know it' s name! Kind regards Helder
