This sequence shows experimental period sticker removal on a 31-bk Yoda. ESB era cards appear to be more porous and absorb more solvent. Removal successful but less than optimal- sticker was cleanly removed but even after 24 hours drying a very faint water-stain "halo" can be seen on extremely close inspection surrounding the removal area in the lighter print colors of the boarder and picture. Lesson learned: do not allow the solven to puddle, penetrate, or soak the cardback. Only soak the sticker itself, allowing to dry before reapplication.
