a26
Alphabet 26 combines the “best” upper and lowercase letters into an alphabet using only 26 symbols.

The impetus for Alphabet 26 was provided in 1949 as he watched his young son labor over his first reader. As he watched, he made a discovery. His son was able to read the first sentence, “Run Pal,” but stumbled over the second sentence “See him run”. Obviously the boy was confused because the symbol R in the first sentence became a totally different symbol ‘r’ for the same sound in the second sentence. Results: Learning to read is that much more difficult. The act of reading is that much slower…A graphic symbol, or for that matter any trademark worth its salt, to be efficient, should be constant.”
