Moving Out
The cover here is a bit misleading as Dorothy doesn't actually die in this issue.
Stephen and Jane go looking for a house, and find the perfect place far from the city. Sherman and Jane are a little less successful, looking at studio apartments that are way out of their price range.
Meanwhile Ed and Irving seem to be getting (back) on solid footing in their comics careers.
This is probably an easy to skip issue of Box Office Poison, because (despite the cover) no truly major events happen - though it is a setup for some things that will be more major; but then that's the way life is, and it wouldn't make sense tor read a slice of life comic only to hit the major events.
