GOTTA MAKE IT STOP EXPANDING THE URL TO SHOW THE IRRELEVENT TEXT.
attached a 1930 advertising paper:
on pg 17, see the Nighthawk 7x24 :
...selected by Harry G. Higbee, Superintendant of the Moose Hill Bird Sanctuary of the Audubon Society, at Sharon, Mass., as the best prism glass at the price to be had, and uses this for the more distant work in the observation of birds and animals.
Retail Price $36.00
Note that in 1930, that was $36.00 in GOLD COINS.
So take the CPI inflation index with a lot of salt:
$572.57 in 2022 has the same purchasing power as $36.00 in 1930.
The total inflation rate from 1930 to 2022 is 1,490.47%. The average inflation rate from 1930 to 2022 is 3.05% per year.
