1940 New York World's Fair Appreciation Certificate + - $115 (Mays Landing, NJ)

1940 New York World's Fair Appreciation Certificate, and Stamp Award Certificates for a Ralph E.
Holdzkom.
Mr.
Holdzkom was a member of the Atlantic City Stamp Club in the 1930's and 1940's (Club disbanded some time in the 1940's).
He received top awards for his "Collection of North Borneo Covers" and "Congo" stamps.
I believe that these are what he loaned for display at the Fair.
My understanding is there were multiple locations that collections were displayed for specific times, depending on their relevance to exhibits.
All certificates are in nice condition, and measure from 7" X 10" to 9" X 11".
Dates for the stamp certificates are in order; Not Marked, 1936, 1940, 1940, & 1941\.
