I have come across lots of post on IH where founders ask for websites providing free Illustrations resources. There are lots of free illustrations resources available on the internet. I have curated a list of all these resources with a mini-review about each of them.
Here is the link to google sheet:-https://docs.google.com/spreadsheets/d/1VCiYme6JTQ5nF7u7z0-V5n8uWnXNslyTVHSDVqqYCFc/edit?usp=sharing
What do think about it? Also, let me know if there is any resource that I have missed that you think should be on the list.
