Adolph died in 1945! Merkle was born in 1954! Obvious photoshop as the two never existed at the same time. I'd love for the photo to be real, but we can't change a timeline; we need to have solid proof or we look like idiots.
The goal is for US to not catch on that they are all related; all in the family. Much harder to prove the family ties as we're seeing here. The stars in Hollywood do the same.
