The cabs with those stickers came from an onsen resort (大江戸温泉物語) that had a free play retro game area for a few years. Whoever installed them at the time must have done a pretty thorough job because most of the machines were very thoroughly cleaned out both internally and externally, but unfortunately some of their cabinets were either set up with free play on ancient games with no attract mode or credit buttons resulting in painfully bad monitor burn over time. Some were lucky and did not suffer that fate, but I've been swapping in monitors into the badly burned cabs as availability permits over time since they are quire nice compared to what you normally see nowadays otherwise.
