Here's a picture showing the relative sizes of the 1929 Anonymous 4/1 Exhibit, the 1931 W517 Mini and the 1931 W517. As mentioned in another thread a while back, the cropping of the photos is different between the W517 and the W517 Mini.
The 1929 Anonymous 4/1 Exhibit has a postcard back (at least mine does), so you should be able to easily distinguish between the 1931 W517 Mini (which is blank-backed) and a cut-up 1929 Anonymous 4/1.
