Here is a picture of the rediscovered papyrus.  Take note of the sketching performed in the missing portions.
Joseph Smith claimed that the papyrus depicted the idolatrous priest of Elkenah 
attempting to offer up Abraham as a sacrifice.  
Based on this assertion, he published Facsimile 1 in the Times and Seasons magazine.  
A copy of Facsimile 1 is shown on the right side.
Even though it is obvious that Facsimile 1 comes from this papyrus,
some Mormons suggest that it could have come from a similar picture 
contained in the parts of the original papyrus that did not survive.
This animation demonstrates that such an argument is baseless.
Note how the images line up almost perfectly.  
Also note that these images were hand drawn on the papyrus, 
so it is inconceivable that even a similar image 
would bare such a close resemblance to Facsimile 1.
Charles Larson, in his book titled “By His Own Hand Upon Papyrus”, 
shows this professional reconstruction of the original scene in the papyrus.  
According to Egyptologists, it is actually a typical embalming scene found in the Egyptian Book of Breathings, 
and depicts Osiris lying on a lion-couch, with the Egyptian God Anubus with a Jackal’s head bending over him.
The Egyptian text surrounding the image support the fact that this is an embalming scene…
and not the attempted sacrifice of Abraham, as Joseph Smith claimed.
This clearly demonstrates that Joseph Smith could not translate Egyptian 
and that the so-called Book of Abraham, believed by the Latter Day Saints to be holy scripture, was a pure fabrication.
