General View of Ton Pentre and Ystrad looking down the valley towards Llwynypia. Gelli Colliery is visible on the right below the mountain on the right. Approximately central just below the top of the mountain is Llwynypia Cottage Homes, later Llwynypia Hospital. Towards the left Penrhys Hill, the road up to Penrhys and over to the Rhondda Fach is visible. The postcard is undated but could be about 1950.
