The Coronet Midget is a small Bakelite subminiature camera produced in the UK in the 1930s, taking pictures on rollfilm in a compact moulded body. The 'Umbrella' refers to a promotional variant tied to an umbrella-related branding, and the blue colourway sits among the rarer finishes Coronet offered alongside the more common black examples.

Sales data for the blue 'Umbrella' Midget is extremely thin: a single UK auction hammer result on record reached £2,400 in 2008, a wholesale saleroom figure that excludes commission. With only one data point, today's value is best treated as indicative rather than a reliable median, and condition, original box and colour authenticity drive what a clean example sells for at auction.
