Here's a bubble. Walking Dead sketch cards. To each their own and obviously rarity is a factor with WD sketch cards, but the prices there are NOT sustainable for the next ~3 years.
The over-saturation of sketch cards isn't going to stop as someone mentioned while companies are moving their boxes.
Like I mentioned on the first page, your safest bet if you are concerned about value is to collect artists who do very few sets or artists who do "hit and runs" (such as the numerous Upper Deck Professionals). The Anthony Tans/Charles Halls/Glebes/etc. will always hold value but it is most certain to go down with significant increases in supply. It is refreshing from an aesthetic and value standpoint seeing Rittenhouse use a revolving door of artists. I think they learned their lessons from Fantastic Four Archives and Batman Archives failures.
