The text in the placard in the Roswell alien slide has been deciphered thanks to the work of the 'Roswell Slides' Research Group, who used the imaging editing software SmartDeblur. Their interpretation of the text:

shirt. Burial wrappings consisted of these small cotton blankets.
Loaned by the MR. Xxxxxx, San Francisco, California
