Free Trade Laws Carved Plaque

This is an interesting relief plaque made of carved stone probably in England around the mid 19th century. I think the stone might be alabaster though I am far from an expert on that matter. The plaque is superbly carved with lots of detail to it. There is an oxen on the left side with two men and a women next to it, another woman is kneeling below with a sickle in her hand after having just cut some wheat off with more wheat on the ground next to her. Another gentleman is sitting on a rock with a lady standing towards the right side under a young oak tree and a central lady sitting while holding a torch - I am sure she is meant to depict lady liberty. I am sure this was made to commemorate the repealing of the Corn Laws in England in 1846. The rim of the circular relief plaque has a leaf garland all around and it has a square base. All one piece! The back has a circular indentation carved into it where the Anti Corn Law League Political Medal was placed. That metal medallion has the words Free Trade with the year 1946 on it. Obviously from Great Britain / United Kingdom . A really interesting plaque! The piece is in superb condition with oxidation to the medal. No other issues and it looks amazing! The square base is about 10 inches wide and 9.875 inches tall. The entire piece is about 0.875 inches thick. Unmarked and I could not find any info on it so not somthing that is common for sure. The repealing of the Corn Laws was the beginning of free Trade so an important point in World history! Please email me for more information or other pictures.
