The Monroe No.7 is an early plate camera produced by Monroe Cameraco., a maker active in the early era of folding plate photography. It is a wooden-bodied folding camera of a type aimed at amateur photographers when new.

Monroe No.7 examples are scarce at UK auction, and the limited hammer record available shows a sale at £62 in 2025, which gives a working reference point for what one of these cameras is worth at saleroom level today. With only a single recorded result, the price a Monroe No.7 sells for can shift considerably with condition, completeness of the bellows and plate holders, and originality of fittings. Buyers should treat that figure as indicative rather than a firm market value.
