My images are sold unframed in a cardboard box and can be purchased on various sites online, from here you can go to the most important ones.
You can browse the most complete Catalogue of Artworks (over 1700) actually at Saatchi & Artfinder.
You can also buy some artworks from Singulart and UK Artists. And, of course, from me.
Pros: These Art Dealers sites offer paying through instalments, promo codes, some free shipping, sales, etc.
Cons: They have higher prices than buying straight from me
