This is wildly incorrect typography that a French speaker would perceive as a spelling error.

• The size of the letter should be the same whether it has an accent or not. The A in à should be identical to the A in image and la.
• The squiggle above the A is an apostrophe. An accent can have variable thickness throughout its length, but it’s almost never curvy (the only fonts I can find with curvy accents are Comic Sans and fonts that simulate handwriting).
• An apostrophe is slanted in the direction of an acute accent (' → ´, ‘ → ´), but it should be a grave accent (ˋ).

This is horribly wrong typography. Whether it’s due to ignorance or sloppy execution or an artistic statement is off-topic here.
