I would collect vintage campers/caravans from all over the globe. All colors/styles/sizes. And, if bribed with bottles of wine, I would even let my friends & family borrow them for camping trips.

I would collect houses. In various styles, in many cities, locations.

I am a huge fan of Anne Rice and New Orleans. I would add her house (which she sold last year) on First Street (in the Garden District in New Orleans) to my collection. For now, I have a picture.

I would collect shoes.....oh...wait....I already do that.

i'm a serious vintage addict, and a professional paper cut artist, & saw this amazing photo in a west elm catalog of a brick wall displaying a collection of framed classic black papercuts (scherenschnitte), a little yellowish & damaged from age - profiles of adults & children... beautiful! ever since i've been trying to create a collection that would go well together for our entrance area. one day i'll get there!

That photo looks like a good start to me. Modern + great cars = :)

Horror memorabilia and vintage magic show items.

I would collect artglass. But instead of having vast display cabinets of it like a museum, I would have a small storage displays with the bulk of the collection carefully integrated into and among the home's interior furnishings.

South Pacific Islands.

My dream collection would be a collection of vintage Japanese etchings and woodblocks.

original art. vintage freak show banners. anything vintage circus/carnival. vintage taxidermy. oddities.

More English and Asian antiques, tea caddies, first addition books.

That photo is screaming my name. Yes, I would collect beautiful vintage cars. I would also collect pre-1900's Japanese paintings and geisha related antiques.

I would collect homes. One in Rancho Palos Verdes, one in Manhattan, one in Tuscany, one in Barcelona, one in Paris, one in the Carribean... Money isn't an issue??? The list goes on!

Lucite handbags and books :)

I'd collect old handmade Persian and other Middle Eastern carpets. And additional rooms to use them in. Oriental antique furniture to keep them company

Experiences. All over the world.

No. No mentions of collections or collecting. It's really too soon. This isn't a collecting blog, it's Apartment Therapy.

Sorry but from the external, it's not hard to imagine that the internal would look like this:

Yeah, collecting and idolizing cars sounds like a -great- idea.

@adventrising, I couldn't agree more. When AT finds a topic they love, they run with it -forever-.

I would collect antique Japanese ivory carvings. I have seen a few on British Antiques Roadshow and find them fascinating.

I would collect fabulous textiles - quilts, suzanis, carpets, etc. And have a place to display them.

I'm planning to collect mid-century art and posters. Ideally, I'd have the full set of Aicher's prints for the 1972 Munich Olympics. A similar thing I plan to collect is copies of Visionaire, or any similar art book.

@ales.ag the inside of the house looks like this

I can't say I would collect anything beyond about 9 pieces of any type of item. If you collect too many of one thing, then you only get those things for your birthday, Christmas, etc. Although a button collection might be fun to display on stretched canvases.

I'd like to collect apartments. One in every major city. But I guess a more feasible collection would be clocks. I love wall clocks, loads of different frames and shapes on one wall would look great.
