There weren't many 40 x 50 picture frames available online, but I found one at Nitori, so I read the reviews and ordered it. First of all, there were reviews saying that the acrylic board and the wooden frame were attached, but please be assured that the wooden frame, acrylic board, white frame and backing board are all separate. You can use the white frame or not, whichever you prefer. However, when you try to hang it up, there is no hook that fits the metal fittings on the back of the frame, so you have to use something else as a substitute. The staff in the store seemed apologetic that they couldn't give a firm answer. I bought some J hooks from Nitori for the time being.
