Here's a list of some affordable must have pieces that normal people like you and I can actually own. To start off I'd like to make it clear that I don't have any bias towards or against Arsham, just objectively some of the cleanest and most iconic pieces in my opinion are:

1. Daniel Arsham x Ikea falling clock

2. Daniel Arsham x Selfridges Broken Ornament 

3. Nike x Daniel Arsham x Cleveland Cavaliers Signed Icon Authentic Jersey
