The last of the Alice rough sheets, this one also date coded February 1950. This has an additional stamp reading February 21, 1950.
Unlike the others we've seen thus far, this one is of the larger size. Most model sheets are 11x14, but this one is larger at 14x17. I don't know why there were two sizes, but there it is. I did have the fortune to see the original of this, way back in the 1990s at an auction in Los Angeles. It was purchased as I recall by a member of the band Crowded House. Go figure.
