I think It is a Delage GL (from Grand Luxe) Skiff Torpedo by Labourdette built in 1924.
I have found some photos and information about the Delage GL Skiff Torpedo by Labourdette in conceptcarz:
The GL was Delage's first super car, designed in 1923 to compete with Rolls-Royce, which had proclaimed itself the 'Best Car in the World.' This new model was given the name GL - meaning 'Grand Luxe' - and put on display at the 1924 Paris Auto Salon. It was given a competitive price and often sold for less than the competition. Unfortunately, the luxury car market was incredibly difficult to crack and the production run was very limited - only 180 chassis were created - from 1924 to 1927 (around 200 examples, including the Grand Sports, were sold from 1924 through 1928). Less than ten are believed to have survived into modern times. The high cost of development had depleted much of Louis Delage's funds. To raise more capital, the company was forced only the Paris stock exchange and the company became 'public.'
The GL stands for grand luxe, and the car is, by the standards of its day, state of the art in every way. The straight-6 cylinder motor with overhead valves can produce 100 bhp and speeds of over 90 mph. The chassis cost $5,370 when new, and the custom coachwork added to the price, making it one of the most expensive luxury cars of its day. The lightweight, custom-built torpedo skiff body was made by Jean-Henri Labourdette of Paris. The body was constructed of ash ribs cross-planked with three layers of mahogany. It is believed to be one of the three original surviving Labourdette skiffs.
