Beistle made three iterations of their 1923 party set: boxed, enveloped and in a booklet form. (The latter was produced with both orange pages and white pages. The color of the pages doesn't seem to impact value.) The boxed and enveloped sets are quite a bit harder to find than the booklet form. The envelopes of the enveloped set are nearly always in poor shape, as was this example. Still, it nearly reached SGV of $400.
