this is an example of where it would look right and not 'out-of-place'. The Tab, shifts, enter and backspace, all have 'iso' legends on ansi-sized mods. there it's fitting, but with the number of gmk/cherry sets out with that specific legend set, it doesn't make a lot of sense and a lot of of classic sets wouldn't match.
A lot of the new sets like with Sherry have both the classic legends for ansi as well as the iso legends on ansi...so handarbeit, and cryllic and the recent dolch sets come with this add on pack.
there is the full recent dolch set (minus my enter and \ caps) and the add on pack is on the right. as you can see, it could work and match this specific set if you chose to...but not most older cherry sets.
Ivan's current and full set/international buy has these 'iso legends' in 'ansi size' as the only option, so if you like then,
place an order. it's a nice large set in a dolch-ish grey color for a great price.
