>>11127020>are plaques expensive?Yes, and on top of the historical landmark, a commemorative manhole was installed in front of lot where the house was that they were renting at the time(It fell into disrepair and was condemned and torn down).
If I remember right, everything together cost over 40,000 USD. All privately funded. Mostly by a local comic shop owner that has been friends with Eastman and Laird since before TMNT was even conceived.
