I gather that what's bothering you is the construction "things traditionally designed." This is something that sounds weird to a lot of people - you've probably read very similar phrases many times, but because you weren't trying to pay attention to the grammar, you never thought about how strange it actually sounds. But in English, both "things that are traditionally designed" and "things traditionally designed" are okay. Here are some example sentences that might make that more clear:
1. Portraits painted by small children don't usually look very good.
2. Portraits that were painted by small children don't usually look very good.
Both of those are totally fine: the first one uses an -ed verb modifier, and the second uses a 'that' modifier.
Now, in your question, you've actually rephrased the sentence to read "things antique" rather than "things traditionally designed." In doing that, you actually made it ungrammatical! "Things antique" is wrong, because "antique" is just an adjective (not an -ed verb like 'designed'), and adjectives generally go before their nouns, not after them.
