This picture can be found on page 53 of US Light Tanks at War 1941-45 by Steven J. Zaloga (Concord). The full caption reads:
A M5A1 from Co. C, 33rd Armored Regiment, 3rd Armored Division, passes a shell-pocked building in the town of Airel on 11 July, as US armor moved up to stop a German attack from Le Desert against the 9th Infantry Div. One of the curious details on this M5A1 is a device located below the hull machine gun . This was apparently added to prevent wire obstructions or communications wire across roads from catching on the hull machine gun and slamming the receiver into the co-driver's legs. (US Army)
A number of other tanks from the same formation appear in the book by Zaloga including C-34, which is given as a decal option in the recent AFV Club M5A1 early kit. The date on that photo is July 8, 1944--perhaps too late for your purpose.
Reading your original post I see you are interested in for 2nd Armored Division vehicles, in general. I cannot give you a definitive list, but I can tell you some vehicles that were available.
M5A1 Stuart: Paraphrasing from the book above, by the time of the Normandy invasion the US Army had largely changed over to the M5A1 Stuart, with over a thousand in France in US Army service by August 1944.
M4 Sherman (75mm) and M4A1 Sherman (75mm): These were the common types in US service for D-Day, including Duplux Drive tanks. By the time of Operation Cobra you start to see 76mm versions. I think the first M4A3s start to arrive around the time of Cobra.
M2, M2A1, M3, M3A1 Half-track: All in service by Normandy and heavily utilized by armored infantry. Many special purpose variants also in use.
M8 Howitzer Motor Carriage: Definitely in Normandy by August.
M7 Priest: Definitely in Normandy. I believe the M12s were rebuilt and deployed a bit later.
M31 ARV: Definitely on Normandy. I believe the M32s came later.
There are lots more, especially support vehicles, that would belong to the division. The US Army standardized it's designs as much as possible, so if you see a vehicle in one armored division the others probably had some too.
