Glad some folks Never threw out their negatives.
These photos come from the Smithsonian Rudy Arnold Photo Collection. If you have an interest and plenty of time, there's something nice for everyone I'm sure.

3,058 color transparencies
Series note:
"This series contains 3,058 4 x 5 inch color transparencies (positive images). Of the 3,058 images in this section, 2,751 have water damage. This damage is visible in the transparencies as areas of color variation, but in general the damage does not obscure the image of the aircraft. The majority of the transparencies in this series depict aircraft (grouped by aircraft type) with folder titles corrected to NASM Aircraft Authority standards. The remaining subject groupings are those believed to have been used by Arnold. Arrangement presents one folder of "Groups of Aircraft" followed by individual aircraft types (alphabetical by manufacturer then model) and ends with subject groups (alphabetical by title).
Digital slideshows are available for the aircraft, aircraft spotters, and airlines subject groupings of this series; each image of a color transparency in the folder appears immediately followed by an image of its NASM-produced transparency envelope. The number prefixed "XRA" appearing in pencil in the upper right corner of each envelope is the NASM image reference number for that color transparency. The digital images in these slideshows were repurposed from scans made by an outside contractor for a commercial product and may show irregular cropping, orientation, and color balance. Irregular color variations within an image are generally the result of damage to and deterioration of the original color transparencies."
