1977 OPC Star Wars #40 Droids rescue their masters!

Centering estimate: left border appears slightly wider than right (~55-60% left), top border appears notably wider than bottom (~65% top), suggesting moderate off-center top-to-bottom; overall within EX range but bottom border is noticeably thin. Blue border shows minor chipping/wear consistent with this issue's known fragility, particularly visible along the bottom edge. Corners appear slightly rounded at three or four tips — not sharp enough for NM territory but not severely blunted, consistent with EX (PSA 5) to EX-MT (PSA 6). Surface gloss appears reduced but no visible creases or staining; print quality is typical for OPC's coarser stock. Back is not visible, so hidden creases or staining cannot be ruled out, which warrants keeping the floor at 4.
