The J & G Meakin pottery was founded in 1851 producing earthenware and ironstone for export to the United States and Australia. James and George (the J and the G) were brothers of Alfred Meakin another English potter. The Meakin name was no longer in use after 1970. In the 1950s they began to make dishware with romantic landscapes.
Look at online auction sales for values. Transferware is not very popular with the buying public of today. The sentimental scenes depicted do not fit into the current fashion for sleek, modern design. Personally, I love it and use Johnson Brother's transferware for every day. (Johnson brothers was founded by a relative of John and George Meakin).
If you want to collect something, make sure you collect what you love, not what you think may be valuable in the future. If you love the old romantic dishware, go for it. It is not fine porcelain, inexpensive, and stands up to use.
