There are no 1926 Ruths shown above. The ones with the name in the box are 1925s; the other is a 1928. Minute color and tone variations are not uncommon in the 1920s Exhibit issues. This is what a 1926 Ehibit looks like. No box around the identifying info. Also, the typeface on the 1925s is sans serif while the typeface on the 1926 has serifs. PSA regularly and routinely screws up its Exhibit identities, as do some auctioneers. The recent Clean Sweep auction had a lot of PC backs where PSA had misidentified the Hartnett as a plain background and I've seen others misidentified as well.
