Wish Book is a home planetarium setup. The 7" diameter star projector had over 60 constellations.
For an extra $19.99 you could buy a plastic hemispherical dome that would actually make
the star projector useful.
According to the U.S. Bureau of Labor Statistics'
the total cost of the star projector and dome ($35.98 in 1969) would equal $224.61
in 2012 money.
