This is also true and I think illustrates a content gap with all these cards regarding the image produced by concave/convex lenses and concave/convex mirrors. We should really be including the relative size of the image for all these cards.

For convex lens and concave mirrors

outside 2f: smaller, inverted, real
between f and 2f: bigger, inverted real,
inside f: bigger, upright, virtual

For concave lens and convex mirrors:
smaller, upright, virtual regardless of distance.

If we make this change instead (including the size) which I definitely prefer, this chard should be:

For a {{c2::concave}} mirror, if the object is {{c3::very close to the mirror (inside the focal point)}}, then the image will be {{c1::bigger}}, {{c1::virtual}}, and {{c1::upright}}.
